97 tj auto no cold shift
 
has anyone had the problem with an auto 4.0 tj not wanting to shift into drive while it is cold, it shifts from first to second fine but when it should go to drive it won't shift until you tach the fool out of it. changed fluid and filter,adjusted throttle shift control cable. no idea unless it's a shift solenoid.any help would be great ...........thanks:confused:

Cold like not warmed up or cold out side?

Try putting it in neutral and revving it to 1300rpm for about 10 seconds. That should get the fluid going.

cold like under 50 degrees and first 2 miles after that usuall??? does fine. i have tried the high idle 1500rpm did not help.......just my luck.....

I had similar problem last year only mine shifted fine cold, and would not shift into drive when warmed up. I changed the trans filter and fluid and included about a pint of Marvel Mystery Oil when refilling trans. After about 10-15 miles it was shifting like new!:D

make sure your running atf 4 or synthetic too. lucas makes a good trnas tune also that you just add in with your current fluid.

clogged filters are the number 1 cause of tranny issues.
