99 GMC Jimmy hesitation problem by nljewell

My Jimmy is hesitating when first taking off, only when engine is cold. And occasionally when cruise is on, the rpm's will surge up alittle. I have changed plugs and wires, put new fuel filter on, replaced egr valve, added some BG44K, and am waiting on a new cap and rotor in the mail. I am out of ideas of what is wrong. Any suggestions? Is it the tranny?

Well I put on my new cap and rotor and that didn't do squat. I took it in for a diag. test this morning and the "mechanic" said he didn't know since there was no check engine light on, so he couldn't check the codes. My next steps are to change coil, temperature sending unit, and change trans. filter. Please reply if you have any ideas.

Transmission Problems Help needed. by ray63

I have a 2000 GMC Jimmy. It started out with my Gas Temp RMP and Speedo guages not workin while driving. They would quit workin for like 10 secs then back to normal. Then it went to not workin and not being able to get my key out of the Ignition. When i cant get my key out of the ignition i would have to disconect the battery. When i would start my truck with the key stuck when i put it in to drive it would shift hard into 2nd gear. While driving it will only shift into 2nd gear and 3rd no overdrive. and usually after driving around 2 miles all the guages will start to work but it still wont shift properly. any help on this would be most welcome

I have a '96 Jimmy (automatic 4x4) that has up till today, been a great vehicle. No problems what so ever. Just regular maintainance. Today while driving along my transmission just quit working completely. No forward or reverse. There were no unusual noises or sounds, I was just driving along when I noticed my rpms going high. Pulled to the side of the road, checked fluids, all which were correct, and when I put the car back in drive... nothing. Pleez help if u have any ideas or suggestions on what the problem could b.

Other than the trans being damaged inside, pump failure, a broken input shaft or possbly the converter stripped which would be unusual...maybe the transfer case somehow got engaged in neutral. If you put in drive then back to park and hear a grinding sound thats what it is...if not somethin just unfortunately broke or stripped in the transmission.

your best bet would be to find a used one you can just throw in instead of doing a rebuild. You can put in a 4 speed maunel with no problems but you'd probabally be happier with the 5

I have the same problem with my 97 Jimmy, just spoke with a Transmission Tech and he said they probably didn't remove the cross-member to get at the last 2 bolts that are hidden by it and probably damaged the solenoids on the bottom valve body when they wriggled the bottom pan off. If you take your Jimmy in to have they engine scanned (free at all Advance Auto Parts stores) it should give the codes to tell you this. Hope this helps.
