    Hello Taco World-

    I recently purchased a used 05 Taco (17k miles, AT) with TRD Supercharger and Extended Warranty-

    I notice that when coasting to a stop the transmission seems to suddenly downshift-hard. Is this normal? On upshifting the trans tends to slip- Is this normal?

    When putting in a factory Supercharger does the stealership reprogram the trans? This is my 1st Toy, after owning Acura, Lexus and Honda and I am not used to this kind of problem since working for GM...Obiwan please send help!

    I'll be honest I just had the TSB in hand...told them that when I was coasting around corners it would downshift hard into first and then have a delayed shift back into second. The guy said alright we'll go ahead and reflash it.......and the change is amazing. I can really tell a difference, the weird shifting was driving me nuts in parking lots.

    Is there a specific TSB for the 2005's? The one that I have seen posted is for the 09's?

    Thanks for the response and assistance
