interchangeable transmission

redo question

i have a 00 grnd prix gtp. the right cv joint broke n broke the housing on the tranny for the axle. i got a used tranny for parts.mine is a 0xab and the parts tranny is a 9xab. im trying to change that outer housing and the inner gear cluster because there is a ring with teeth on outer edge of thegear cluster that broke.the part number is different from one to the other. not sure if there is a difference in the part or because of the year. on the gear cluster of my tranny it has # 24202790R2 parts tranny it is 24202790R4. r these parts inter changeable or can i take that ring with teeth on the outer edge off n put on my gear cluster. they look the same but sure about number of teeth in the gear cluster. that outer ring with teeth is the same.

i think what you are talking about is item 42 in the drawing i'm sending. That is the reluctor wheel for the speeed sensor and they both have to be the same on which ever trans you are putting in or taking out of the car. this is a 4T165 transmission or should be. sound slike you can't take the ring off for the vss.

it has same number of teeth on it as other one. it is a ring about 4 inches around. i was worried about the gears that are like spider gears, 4 inside that housing. it all looks to be the same. just trying to make sure what it interchangable.

ok if thats' the case then it's ok, i was under the thinking that one was like a speedo drive and theother for a vss. as long as they have same teeth you shold be ok. don't beat the hell out of hte thing though installing ituse a hammer and wooden block an dtap it getnly until it seats. the thing you are talking about is the reare end, make sure your acle will gointo it and your other stuff will fit.

yes i guess it would be the rear end. im hoping to just switch the whole thing so i dont break it trying to get it off n back on. was just wanting to no if they inter change. thanks

im going to put in the whole rear end. counted teeth n all have the same. then i dont need to take the chance of breaking that part. shaft sizes appear to be the same. so then the speedometer should read accurate. dealer told me on the tag it says 0xab that 0 is the gear ratio bot the other tranny is a 9xab but have same number of teeth. so is that the gear ratio. 0xab is to be 2.93 ratio. so i dont no.but they appear to be the same. thanks

im trying to put the rear end back into the transmission. having problems getting all the teeth on the rear end to line back up with the gears still in the trans. is there anyhing special i need to do or just push n turn until everything lines up n goes backn together all the way. the gears in the rear end should just be flush with the gears they mesh with inside to be all the way in correct.it seems they are just starting to hit on the teeth inside on the ring they mesh with. so dont if its those that r not going together or if i hit inside with something else not letting it go anyfurther. do u have a diagram of it or anything so i can see it. my book dont cover tranny. thanks craig

here is a chart... for the back end of trans.....

so basicly u just push and turn to get all the gears to mesh. i was also wondering from one tranny to the other if the rear end could be bigger around on the planetary pinion gear, but the gears inside have same amount of teeth. could there be a difference. thanks

shouldn't be

so just have to push n turn until everything meshes together?

can i get my question answered. and was also wondering does anything fall out of place when u pull the rear end out. or should it just slide back in with like turning and pushing to get all the gears meshed. had to pull rear end with the axle when the cv joint broke cause it broke the outer housing n didnt have a way to seperate them in the car. thanks

i'm sure thrust washers will fall out of place and maybe a few other things. we aren't here to rebuild the trans for you. everything shold mesh together on assembly.

sorry i thought you answered questions. it looks like a bearing for the end of the differential shaft inside is hanging down n is it possible to pull yhe next piece out that the rear end goes into without making a big mess. thank you for answering my question.

i cna't really see it so i can't give yo an answer on that one. but from your description it sounds like there is going to be heavier damage than what youare anticipating. this trans has to com eall the way apart from teh torque converter to the rear end as it gose in from that way. My best advice that i can give you is to see if your local library has a manual of a close year that will cover transmissions. Normally a factory manual.or you can go on the site here and download the mitchell manual for around $10 for 3 days i think it is, download the overhaul area or print it as it allows you to do that.it has pictures and the whole 9 yards. I cna't help you any further.

is there anybody else i can talk to about this. thanks

you can try to repostbut it's hard for us to try to see what you aredoing or trying to describe. why dont'youjust put the trans in you are trying to rob parts from
. it's obvious you really aren't sure of what you are doing and this should be done by a pro.

i went to school in 1979 and 80 for this **** didnt have front wheel drive then so yes i can work on cars just didnt want to switch whole thing when i no i didnt have to. its just a roller bearing the shaft for the rear end looks like it fell a little lower than where the shaft should go into. i just need more info on what is inside thewre n how much can be taken apart thru that side without messing it up . it is apparrent that the differential can come out without a problem. how much after that can come out without something falling apart and having to take apart the whole thing. that is what i need to no. or more pics from what u already gave me. thanks

to bad this wasnt a saturn. those guys r very helpful n ive never had a problem with them helping me,very polite and answered every thing i asked with success

you have the blow up pic that isent ont eh very first or second email you should refer to that.

and it would look like #24 would be hanging down a little.is it possible to take out like 31 n 32or whatever ahead of rear end thru that side without messing some thing up. how many parts can actually come out that side n be put back in without having the tranny out n all tore apart if that has dropped down or is it possible for that to drop a little. thanks

the reason i was seeing the bearing inside looked like it was hanging down was because when i pushing rear end back in it was pushing the other axle out and it was tipping from the weight hanging from it.so i have to hold it in some how to put it together or take that axle out, then start putting it back together and hope the gears all mesh.

think maybe u should go find a pontiac tranny to work on to brush up ur skills a little. got it together just fine. it was the other axle because there was nothing to hold it in.

I have a 2000 Pontiac Grand Prix GT that needs a new transmission. It has a 3.8L V6 engine not supercharged. I am going to get a transmission from a salvage yard, but they need to know the type of transmission. I know it is a 4T65E based off the vin number. However I am supposed to tell them if it is a BCB or BRB. I have called every local mechanic and asked where to find this information and have searched the internet trying to compare diagrams. This information is NOT to be found. Not on any labels on the transmission, not on a label in the glove box, doors, or inside the trunk. I am lost. So, I guess since I cant figure whether it is a BCB or BRB, my question is, can they be interchanged? If I were to get either type of transmission from a salvage yard for the same year, model and make...would it work? If not, is there any other possible way to figure out the type myself without having to take the car to a mechanic? Thank you for your time.

if you have a "W" code n your vin number it's t465e

I already know that it is a 4T65E based off the vin, that was all I could find out. I need to know if it is BCB or BRB. Not to be rude, but my first question has what I am wanting to find out, to save typing. Thanks

we don't have any idea bout the bcb or brb tose are usaualy tags an dare paper . thee may be anumber stamped by the pan someplace that will give that. check for a plate as in pic that may have it.

I have a transmission problem its a bit drawn out but i have to explain. Just bought this 99 grand prix gt v6 3.8l, the guy said he'd dropped an engine with 80,000 miles in it. which is great the engine sounds beautiful but this might be my problem. The engine was from a 97 grand prix i believe. I know he said 97. Tomorrow i will search the engine and find out for sure. I noticed after driving it awhile it shifted hard going up-shift and down-shift. I'm hoping it's just trash and a new filter and fluid will fix it, but i was searching on eBay for transmissions in case i need one and according to that the 97 engine is not compatible with the 99 transmission. Tonight it got stuck in 2nd gear for about 2 blocks at least and finally kicked into third and drove fine the rest of the way other than the hard shifting. So i need to know a few things... 1) is this 97 engine really not compatible with the 99 trans and is it even possible that it would still work just not work right? 2) do i need to get the 97 trans or another compatible trans and if so will i need to replace anything on the engine side that might have been damaged from this?

you need to have engine and trans compatible with your computer. it seems tha tit wold be easier to put all the correct sensors in engine. check tosee if they are all hooked up and scan for codes first. it may be the harness isn't plugged in correctly

TY today i had diagnostics ran on it and kind of figured that out it came up with one code only ... PO502 (low input speed sensor) showed twice one old and the other pending then we looked up the computers and for 97 it was 4T60E for 99 4T65E
So now I'm just stumped on where to go from here is there a way to adapt it where it will get the right voltage to the speed sensor? Will it be as simple as just changing the speed sensor? I'm lost when it comes to this electrical stuff. This is the newest car I've ever owned or worked on. I believe there is a trans shop here that does free diagnostics so im gonna see what their ideas are tomorrow hopefully. Mechanically I think the trans is still good the fluid i drained out was pretty clean. Not alot of metal shavings or any large shavings... there were small pebbles in the pan? lol no idea how that happened but i dont think they ever made it through the filter or thered have been more metal shavings. Changed the filter and put lucas and new trans fluid it shifts right now not hard like b4 but just every now and then it doesnt want to upshift from first until 3.5 rpms when normally it will shift a little past 2. Thats another thing throwin me for a loop why would it get the right voltage and shift when its supposed to sometimes and others not until its at higher rpm?

the 4t60 and 4t65 may not be tht much different like maybe a another clutch or so in it. they did have a 4t65 in 97 just not for the 3.1L so it shouldn't be that much different however after looking at wiring diagram it looks as if the 4t65 has a pressure control solenoid in it which the 4t60 does not. I'm sure a trans guy can figure this out alot better than me as they deal in them all the time.

Will a 99 Grand prix 3800 transmission fit a 2002 GTP?

Call local junkyard and ask, they have interchangeability info on all cars.

While it will probably fit, (3800 to 3800) it may not be stout enough to handle the supercharger power.

I was wondering if a 96 tranny would fit into a 98. would taking two carsand making them one be okay. and if not what would you suggest if the tranny isnt moving into 3rd gear and is reving high ?

Contact local junkyard and see what years' transmissions are interchangeable.

Some trans shops are offering free diagnosis, take car to shop and get a diagnosis, could be something simple like a shift solenoid, but generally when a trans starts slipping it is not a good (or cheap) sign.
