Auto Tranny Hesitates When Shifting

Hello,

I'm new to this forum and new to Jeep's altogether. I have a '98 GC Laredo w/ I-6 and Auto tranny, and whenever I move from a start the transmission hesitates from 1st to 2nd, and a little bit from 2nd to 3rd. It also feels like it shifts to 4th a little too early (like right after it shifts to 3rd). It's also rough going into reverse. I've checked tranny fluid level and condition, and all is good. I've also just done a full tune-up on it (stock plugs (Champion RC12LYC, wires (Bosch), cap, rotor, filters, etc). It feels like this problem started shortly after doing the tune-up (when I test drove it, these problems didn't occur and it shifted smoothly, save for the rough reverse). The car has a little over 100k miles on it. What might the problem be? Thanks.

If your trany is slipping (rpms jump about 1000 higher than they should at the beginning of each new shift), then your trany is shot. Mine did this at 140k miles. I adjusted the bands and changed the fluid with no avail.

Hesitating between shifts, shifting early or late are entirely different then slipping between gears (which usually indicates wasted clutch packs and a worn out tranny). Best advice would be to have a competent tranny shop check it out. Chances are it could be something minor if it is not slipping as stated above.
