yeah, thats with the converter locked tho. im at 2750 in 3rd with the converter locked at 65, in theory, going from 1:1 to .75:1 (converter locked in OD) i should be at about 2100, but im not getting OD with the TCU

im having a hell of a time getting my jeep running right. i have a 2001 that i bought with a blown trans, so i threw a trans from a 91 in it and its running off a 95 tcu. and with the tcu connected i get 1st, 2nd, 3rd and 3rd w/lock up, but it stays locked in 3rd when i let my foot off the...

does anyone know how many RPM the engine drops at a given speed when an AW4 shifts from 3rd to 4th with the converter unlocked? Thanks

i understand that not everyone knows exactly what the solenoids do, other than make the transmission shift. let me try to explain. Solenoid 3 (S3) does absolutely nothing for shifting, it is for the torque converter lockup, and nothing else. Solenoid 1 and 2 (S1 and S2) are what control the...

thats what Im thinking. probably jsut going to have to grab another trans. or sell the jeep, dont have time for this stuff right now.

i cant see it being the solenoids. over drive is both solenoids off. and i have perfect shifts 1-2 2-3 3-2 and 2-1. If either were stuck on I would loose other gears. the tcu wiring is correct, everything checked atleast 5 times now. is there something to actually check about the tcu...

i dont have OD at all with the tcu connected. and solenoids kinda test themselves, if you have atleast 3 gears they are working

first, see here for the specs and original problem http://naxja.org/forum/showthread.php?t=1011413 now that that is fixed, i have no overdrive. with the tcu unplugged i get 1st in 1-2, 3rd in 3, and a 200-250rpm drop shifting into D. with the TCU connected the best i get is 3rd with lock up...

so did we. apparently all they got rid of was the switch. so if you wanted to wire a valet mode into your jeep you could just run a switch on that wire. 12v is power mode (normal mode) and just leaving it open is comfort mode (aka shifts at 3100)

problem solved. the power mode wire must be supplied 12v, even tho the fsm says not connected. it was basically in comfort mode.

this thread is old as hell, but, i dont care. its linked to alot, and is full of wrong information. ALL cherokees with an AW4 (1987-2001) have a TCU. 87-96 are behind the passangers side dash. 97-01 TCU's are located under the steering column. the myth that the pcm controls the AW4 in 97-01...

TV cable is adjusted and working, i even disconnected it and extended it all the way, bangs into gear when shifting at idle, same 3100 rpm tps is off slightly from my expectations with the older jeeps, this one is coming it at .90v closed 4.10v open. not adjustable of course.

Been a LONG time since ive been here. but i grabbed another XJ. 2001, blown AW4 swapped in an AW4 from a 1991 running it off a 1995 TCU jeep shifts perfectly, except that at WOT the max rpm the jeep will see is 3100-3200 in 1-2 it will go to redline. the ONLY thing i can think of at all...

fill your tank, on object at rest stays at rest..... gas is an object technical term.... it "sloshes"

the rear kit includes crossmember, mounts, spring buckets and arms

yes post some pics for sure, i love your set up, just cutting the floor isnt an option. the difference is lowering the lower frame mounts 1" and raising the upper frame mounts 1". but i lowered the upper axle mount some and pulled them forward, and i got 103% antisquat and the frame mounts...

oh yeah, we know, were working on it slowly. to answer the questions here, lowers are 2"x.25 DOM uppers are 1.5"x.25" DOM, RE joints on the axle end, rubber bushings on the frame end. rear crossmember is NOT removable, front is, belly pan is completly bolt up

As some of you know, were starting to sell kits for XJ's. 3 link fronts, 4 link rears. I was wondering what some of your opinions are for rear 4 links on antisquat numbers and such. So far i have 2 designs, heres the numbers Anti-Squat 103.15 RC Slope 0.0954"/in RC Height 24.562" RC...

most likely cause, idle air control, search for how to clean it.
