Streetracerx1911 Posted April 18 Share Posted April 18 I swapped an Xterra Transmission into my 4x4 and when the car warms up, it won't go into higher gears...is this a limp mode condition...do I need to get the TCM from an Xterra, and install it on my 94 Pathfinder...Thank You Link to comment Share on other sites More sharing options...
Slartibartfast Posted April 19 Share Posted April 19 From what I've read, no, it should be a simple plug-and-play. Limp mode puts it in third IIRC. Does the light in the E-AT switch flash when you start the truck? Check your transmission fluid level when the transmission is warm. Too high or too low can both make a slushbox act weird, and they're easy to overfill. I filled mine to what seemed about right when it was cold and had to drain about a quart once it warmed up to get the level correct on the dipstick.

adamzan Posted April 24 Share Posted April 24 (edited) What gears do you have, and not have? IIRC on mine the neutral safety switch (range sensor as nissan calls it) was broken and the tcm didn't know what position the shifter was in. It caused me to have 1-3 and 4 only when a certain amount of throttle was applied. Torque converter lock up didn't work at all. I may be misremembering the gears because this was over a decade ago now. Edited April 24 by adamzan Link to comment Share on other sites More sharing options...

Streetracerx1911 Posted Wednesday at 08:36 AM Share Posted Wednesday at 08:36 AM once the truck warms up, i have 1st and 2nd gear...i went to the junk yard and saw that the xterras all had tcm's, under the dash, near the brake pedal...i also had to switch out the original stock shifter, since the cable, was too short...i used once from an xterra...but i didn't reconnect, all of those wires either...so maybe that has something to do with this issue, of it going into limp mode...On another note, it runs GREAT!!! until it warms up...Shifts really smooth Link to comment Share on other sites More sharing options...
