Coming home tonight the GN is running great, shifting great. Then I feel a sudden surge/clunk going around a 90 degree turn. It feels like to shifted right from 1st to 3rd with no second or maybe what i felt was the TCC locking at a really slow speed (is that even possible?) So then I drove it some more from a stop at a slow speed to feel the shifts and it still felt like a very short 2nd gear, like it went right to third and would bog the car down. If I run thru the gears manually they work ok. I check the tranny fluid level when I goy home and its full, light red in color and no burnt smell...Any thoughts or help would be greatly apprieciated!!!

Do you mean the TCC solenoid? Is there a TCC sensor? Thanks!

That's what I'd try replacing first.

There are a 3rd gear, and a 4th gear, pressure switch in the tranny to tell the ecm what gear the tranny is in.

The TCC solenoid seems to be the weak spot, and if it *sticks* the TCC can stay locked *on*.
