AW4 Speed Sensor?

[ghetdjc320]

Does the AW4 have a speed sensor it uses internally for shift points? Have an aw4 in my 91 4x4. I know the vss is in the tcase but was wondering if tcu is reading another internal tranny speed sensor. My shift points are just not right.

It’s on the drivers side of the transmission  behind the 4wd shifter linkage pivot bracket  that mounts to the transmission and tcase . 
 

I’ve had a couple jeeps over the years that didn’t shift correct. Normally the fix for mine was replaced on the throttle positioning sensor or the detent cable

but IF it´s doing the shifts then the throttle body cable and/or TPS are out of adjusment, a faulty speed sensor will make the transmission not shift at all

I was wondering if the tcu needed reprogramming to accommodate for tire size. I did adjust the transmission cable and the throttle position sensor is a new Mopar unit and is within spec. I was about to install the transgo shift kit and probably still will but was wondering if these shifts could be sorted out in another way.

 

it’s very slow to kick down and very quick to go to a numerically higher gear
