Default Where is the TCU located on my 88 cherokee?

i changed out my TPS and adjusted the input/output accordingly but im still having the trans stick in a gear and not shifting once in a while

my input voltage was a little low 4.55 instead of the regular 5?? is that ok?

i figured id check out the TCU for bad grounds or something.

Caged, your credibility is always strong with me.
I just got back from drive and from the noise and nonsense I was sure the driver must be sitting in the back seat, inlaws eh, lolol
DaveV, which year Cherokee is your trans module suspect on? I have a spare for and AW4 if you need.
Which gear is long shift, or is that variable.
Last time trans fluid and filter changed? Is there a trans power switch on your dash activating and raising the shift points?
Does it act same cold and warmed up?
