The computer will then, by default, set maximum line pressure for the transmission, which will most likely give you the hard 1-2 shift. The P1870 will also inhibit fourth gear from applying.
Yup, check connections, at computer and at the TPS. If you know how to check the TPS with a voltmeter, that would be a good idea, but it most likely needs to be replaced. Clear codes, take it for a spin and see what happens. Tranny flush is a good idea, fluid and filter.

Sorry I don't know much about cars, what is the TCC? Also, how do I clear the codes? I already postponed the tranny appointment. Tomorrow II'm taking it in to get the tranny flushed, new TPS and hopefully they know how to clear the codes. Sound good??? I really appreciate everyone's help. I'm off to Foxwoods casino to see if I could win enough for a tranny.......Just in case. Thanks for everything, Maria
