Transmission not shift first to second gear properly and refuse to go to fourth gear

Most of these are related to valve body electrical problems, shift valve, converter lock up clutch check and clean all terminals in the harness plug at the transmission and make sure that this plus is tight see if that improves matters.

Thank you so much for your response, cleaning and check all the plug have been done, but these just slightly improve still having the same problem. what should i done next? thank you.

It sounds like you have a shift solenoid that is not working. I would test through the winding's to see if there is continuity. Also, check the four fuses that run the system. You can see which ones from the diagram below.

Here is a guide to help us get started:

Also, there is a ranger selector switch I would test as well.

Here is the transmission wiring diagrams so you can get started.

Check out the diagrams (below).

Please let us know what happens.

Thank you for your reply. i am planing to check and change the torque converter Clutch solenoid and pressure control solenoid. After i have checked it i will reply to you back.

Thank you,

Dear, i have just check the wire and change the torque converter clutch and pressure control solenoid but the problem still exist. now planing to change the shift solenoid. but i do not understand the shift solenoid, i have two shift solenoid and my transmission type is JF405E.
Thank you,

The wiring diagram shows five solenoids? Can you upload pictures oft he valve body so I can point them out?

dear,

this is my valve body, totaly it is only 4 solenoid, 1 for tcc , 1 for pressure cotrol solenoid and 2 for shift solenoid, dont understand hiw shift work with that 2 solenoid. on more think i just notice that my actual valve body was missing (just a hole but nothing there) the one at the re circle, what it is function and what if it dont have that one?

thank you
sothy

The hole is weird there was nothing in the pan that maybe has fallen out?

Dear Mr. Ken

Yes that is weird cos i see the other valve body the same to my car was fill with some cover (the first picture), but what its function and what happen when it is dont have like mine?

Thank you so much
Sothy

Not sure. there was nothing in the pan like someone put it together that way? Maybe is for a extra gear like 5th and you don't have it?

i dont know but i have checked the same valve body only that thing is different from mine. same make same year same model, but the differrent is only that one. and i have change all the solenoid but its has the same issue.

It is beginning to sounds like you have an internal lip seal or clutch pack that is going out. It might be time for a rebuild.

so if i have the spare part for that hole, i should be place. thx u very much

Did you do the rebuild yourself? Seems like a valve is missing from the area mentioned.

Thank you for your reply.
No, i didn't rebuild my self.
Actually my tran was rebuild in the garage and change with the new tran but not the same one just the similar one (mine is Kia Picanto 2004, Workman tran was Suzuki Wagon r but the tran was the same model JF405E), after that it good but have mention problem above. Latter i try to check on valve body on my own and than i seeing this hole.
Thank you

I would try a rebuild valve body and look to see if there is a difference.

Here is a diagrams on how to change it out.

Please run this test and get back to us.

Cheers, Ken

Thank you very much will try that and get back to you soon. cheers. :D

dear,
i have one more question according to obd2 scanner, my car show me my engine coolant -49c and i cant check my tran fluid temp. what is wrong with that?

thank you
sothy

O man, that can cause the issue for sure. I would replace the sensor here is a guide to help show you what you are in for when doing the job.

Here is the location.

Please run down this guide and report back

Cheers, Ken

oh ok thx you, will report back to you.

dear, i have changed the new sensor already but when i check temp still got -49c .

dear, i just change and add some items in valve body, now it back to work well.

thank you

ok, well done, transmissions can be tricky things to work on,

Dear sir,

I have sth dont understand after everything going good but when i try to drive at high speed 100 to 110 km/h my rev is going to 3500-3700rpm is it normal or something problem? and i want to know that what is the rang speed for gear changing? and my idle rev is 750 - 800rpm

thank you
sothy

I just drive at high speed yesterday and checked with my mini obd2 scanner and it shows the code P0741. What should I do with this and what happen if i drive with this code?

thank you
sothu

Torque converter lock up clutch is not coming in, check that he solenoid for this function is ok.

thank you for reply. you mean the torque converter clutch solenoide , it that one i been changed already.

initaly it was 1st to second gear that is not the TTC solenoid, the trouble is i have no idea as to what you have been doing with the transmission, i can only work on the codes and symptoms, you now need to check that he TTC is powering up and activating at the correct time.
