first to second shift problem

Hi guys new to your site so be kind. I did a search first and couldn't find any info so now I need some help. First I'm tring to help my parents with their Jeep. It is a 2000 Jeep Grand Cheerokee 4.0L 4x4 with I believe R42 trans. They are having problems with it shifting back and forth from first to second. It gets to the point where it should shift to second but its like it gets confused and shifts back and forth a couple of times before staing in second. They have had it to the dealership (poor service center) and they can't figurre out whats wrong with it. When they first had it in there they said the fluid pressure was low. They said they fixed that. Its also had a fluid flush and filter change, also changed govenor soliniod and sensor. So any help would be great. Thanks.

try taking it to tranny shop and see what they say. Most shops will do free analysis. I had this prob im my 42re and it needed rebuilt. Something to do with throttle body in tranny. Hope this helps.

Governor pressure solenoid and governor pressure switch.

Replace both at the same time.

Your cost would be about $100 and a half hour of your time.
