GMC Jimmy Transmission Problems

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?

| 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. | |

I had my tranny fluid and filter changed a few days ago they said everything looked good now my engine light came on put it in drive and feels like its draging rpms revs really high just to start moving like someone is pulling you as your trying to drive away it dose that in all gears but rev 4hi dose it but not 4lo any ideas would be great
