tryin to sell me a transmission out of a jimmy that was submerged in water
 
I wouldn't go anywhere near it. Beyond possible water damage, transmissions don't ordinarily become submerged without serious stress on the entire system.

I have a 99 GMC Jimmy a couple of weeks ago the check engine light came on and it started to hesitate when I would accelerate from a stop. I took it to auto zone they could not read anything the thing in my car they hook the machine up to is messed up. Anyways my car now dies. I start it and it goes a little bit then dies again. Has anyone had this happen to them? Does anyone know what it might be?

Hi, I have a buddy with a 95 jimmy that's doing the exact same thing. Any chance you ever figured out what was causing the problem?
 
My friend is a disabled Vietnam vet and on a budget so i was hoping i could help him out with this.
 
  Thanks

i've got a 1998 jimmy with 2wd only, the transmission seems to surge between gears when at 45 mph and up. it feels like it down shifts for a second, then finds the correct gear again. it does this every five seconds or so even when its on cruise control... anyone got a suggestion?

95 jimmy sle not shifting after overheating by jaqdadi

ok, I have a 95 jimmy sle 4.3, 4l60e auto, w\111K, the vehicle as a whole is in excellent shape, I let my mother drive it to boston and back (40 mile each way) on the way back the water pump blew and dumped all the fluid and also the tranny overheated and flushed a bunch of it's fluid, by the time she noticed the needle was in the red and the vehicle had no power. Towed it home and replaced the water pump, fortunately no damage to the engine as it is running perfect, added some tranny fluid as well, but, now it won't move when I shift it in to 1st, ther is some minor movement, a few straining inches, in any other forward gear I get nothing, when I first start it I can get a few feet in reverse but that's it. I have no problem tearing the engine apart and putting it back together, however my tranny work is limited and so is my budget. I have all the tools and space to work on it. I have replaced solenoids, filters , flywheels, etc.. in many other vehicles so I am not affraid to open this up I would just like to know where to look if possible? thanks.

I just put it up on jacks and started it, it shifts and the tires move in forward or reverse, but when on the ground nothing. I also am draining the fluid and I have never seen tranny fluid this dark brown and very thick. It's like 80 deg and sunny out and this stuff looks like molasses on a co;d day.

Actually i'll be learning how to do a full rebuid on the 4l60e transmission, this one must have gotten pretty hot cause one of the electrical connectors was completely melted off and the fluid in the pan was like graphite sludge, so in the end i'm probably gonna get it right, but I know it's gonna be painful. If anyone was considering any suggestions, thanks.
