So yea this is my first thread and i don't really know what I'm doing haha, but i have a 2000 Jeep Grand Cherokee with the 4.0 and recently its been having a really hard time shifting in the first and second, especially when i go around turns it revs up real high then goes into gear...Any suggestions??
Nlabs, I have the very same Jeep... 2000 with the 4.0L. I bought this Jeep new, and the transmission has always acted exactly as you describe unless I overfill it by a quart, maybe a quart-and-a-half. I've put over 215,000 miles on it, still runs great so I guess the extra ATF doesn's hurt anything.
The road goes on forever, the party never ends....
+1 on adding more fluid. I have the 4.0 as well and experienced the exact shifting problem while turning left. Added ATF+4 fluid a little at a time until the rough shifting went away. I thought maybe it had something to do after adding a 2" lift.
yea the same here im completely stock, but next week im getting 31s (i hope to god they dont rub) and then in 3 months im getting the IRO 3 inch lift, so im just going to service in the next week or so and get the lucas additive my mechanic was talking about and hope for the best!
I have an 04 Special edition with the 4.0 and im having the same problem. i dropped the pan changed filter and fluid to no avail im going to add lucas to see if that helps. was told it was a tps problem so i changed it and that didnt help either. another mechanic told me it was my aic valve so im going to change it in the morning. what does the transmission speed sensor look like? the jeep has 160k on it and thought maybe the tranny just going bad but if i drive the **** out of it i have no problems. any advice is appreciated. thanks
