99 JGCL check light and jerking transmission

plusa did pass the time by typing:

Check the transmission fluid level for starters.

And the color and smell and consistency (foamy, milky) of the fluid in addition to the level...

A transmitter wired wrong will cause that.

That also maybe could be caused by the TPS. The TPS controls some shift points, I don't know about the neutral shift though.... The electrical connection on it can always benefit from a clean though. Contact cleaner is best but WD40 will do in a pinch.

The Jeep transmission also does 'NOT' have a high water vent like the diffs and t-case so you should make sure it isn't half full of water... It will look like purple milkshake if water is in the fluid.

I'd go with the gas cap if it weren't for the transmission also going berserk. For that I'd almost guess a loose wire/ground somewhere as I've not heard of TPS or CPS being that bizarre.

Bill,

Thanks. The code P0700 indicates transmission module fault code, and I guess can be pulled by a dealer. The fault is often caused by transmission input or output speed sensors. All this I have got from your link. I'll try to clean connectors, and if this will not work, replace sensors (or sensor - they are identical.

Re transmission fluid, as some suggested, that was the first thing I've checked - clean, red, and correct level.

With the new ATF+4, the color is no longer an indicator.
