My car is 2001 TL, 170k, runs perfect until yesterday. I don't have much experience on diagnosis. My car's engine light and TCS light were on simultaneously when we drive a in parking lot, after a 2~3 mile drive on a bumpy road. After restart the car, TCS light is off. engine light is on again.

When driving, feel hesitation exist during fast acceleration. Feel like it is not as powerful as before. But if I drive smoothly, the car works fine.

Get the code p1676 and p1750. The dealer suggest replace the transmission and quote me $4000. Got scared... Is it really a transmission problem? What the normal price to rebuilt or replace a transmission? Thanks.
