How do you test shift module and or shift solenoids on a 87 pathfinder 4X4. Won't shift out of 1st gear not even manually.

Here you are, the first link is to the factory service manual's testing procedure and overall parts layout, the second one is a copy of Nissan's factory transmission manual for the RE4R01A automatic transmission. They open with Adobe PDF. Hopefully your Pathfinder has the 4-speed auto, not the 3-speed? The RE4R01A is the 4-speed.

Those are rare and problematic. They didn't use the 3-speed past 87. Sorry.

does it shift manually?

striperdad

No it didn"t shift manually. Had the tranny rebuilt for 1700. Now I need a Y pipe.

I just picked up an 87 Pathy and am wondering what rpm's is normal at 55mph. The trans completes the first 2 shifts fine but has never made a transfer to the 3 shift. It currently turns about 3500 rpm at 55mph. It does not have the power shif button.

Mine is doing the same thing I got underneath to fine that my torque converter solenoid wires were ripped out .....guess it got caught on something while 4 wheeling. I know that the throttle position has lots to do with the shifting usually around 50-55 it shifts to the 3rd shift can you let off the throttle a little to see if it will shift then slowly accelerate?

I am waiting on the part now ....i will let you know if that fixes it
