I had a code come up after I got my new trans in, P1870, which applies to the tcc slippage....any way cleared it several times, when it was cleared car drove fine....now I don't have any codes (I scanned it) but I have no 2nd or 4th gear....I have reverse....whats the problem, how do I fix it and how much is it gonna cost??! ANYONE!!!

mechanical failure of the sun shell or band is probable cause.this will not allow the planetaries in the rear of the trans to be overdriven in 2nd and 4th to produce these ratios.also verify that the shift valve is not stuck or the solenoid is failed .sometimes the solenoid will fail and not trip a code if the resistance the computer measures across it is not affected by the mechanical failure of the solenoid.

First question (did you just put a converter in). If so you just have a tuning issue. If not the shift solenoids are probably bad and need to be changed, no big deal 30 dollar part and all you have to do is remove the trans pan, take out the retaining clip and slide the old one out and disconnect the power cable, install the new one and connect the power cable, install trans pan and refill fluid.
