Automatic Transmission and Blown Fuses?

Hi,

Certainly, the fuses could be related. Which fuses were they and where are they located? Also, when you shift, is the shift cable moving the shift lever on the transmission?

I attached the wiring schematic for the transmission below. I highlighted the fuses I feel may be a cause. Let me know if they are blown and which others are. Also, let me know if the gear indicator is working properly.

Take care,

Joe

Joe, thanks for your response. When I replaced the blown and scorched fuses, I didn't write down which ones were blown. I know I replaced 4 of them vertically on the far-left column as you look at the fuse panel. Numbers 13, 17, 21, 25, and 24 I changed (they look different than the others). I would have changed more but I ran out of fuses. The ones you highlighted in the attachments I will double check and let you know.

The gear selector on the transmission moves when the gear selector on the steering column is manipulated. This is the 2nd transmission I have installed since I got the ranger. The first one when put in gear didn't feel or sound like the gears engaged the same as the 2nd, that along with finding out about the fuses, and possible alternator issue since I have to jump the ranger every time I start it, lead me to find this website.

I completely understand since the transmission has electronic components it could be influenced by whatever caused the electrical issue. I'm hoping to find out what steps I need to take to diagnose and repair the issues. To me it's really odd when the original transmission worked fine except for in reverse, and I'm assuming the alternator was charging the system, I never had a need to find out until the issues with the two transmissions took me to the fuse panel. The previous owner had someone try to diagnose the transmission issue. When I bought the ranger the dash panel around the steering column was off and you could tell someone had been poking around inside.

Hi,

The interesting thing here is you mentioned the failed fuses and added the others were scorched. That shouldn't happen.

I looked up the fuses you mentioned and none of them are related directly to the transmission. See pic below. When you installed the new fuses, did you check if there was power to them, specifically fuse 25 (GEM)? If not, confirm it has power. Also, the other fuses are of interest. Fuse 24 should be empty on this vehicle. It is for the clutch pedal position switch.

Do this. Disconnect the connector at the transmission and check pins 1, 10, and 11 for power with the key on. See pic 2.

Let me know what you find.

Okay, sorry for the delay in response, been busy as heck lately.

No power to either of the three pins. I had the ignition key turned to on for power and I grounded the clamp of the probe to the frame. Each of the 3 female plugs were lights out.

Hi,

If you aren't getting power, make sure the GEM fuse you replaced has power to and from it. If it does, we have an open between the GEM and transmission. Likely, we have a short that is what caused the fuse to fail.

Let me know.

Joe
