Aftermarket Transmission Controllers

[South Africa]

Hi

I am considering using one of the aftermarket trnasmission controllers and am interseted to know if anyone has any experience with the various models available. Any feedback will be appreciated.

I got a switch for my '98 TA with an AT. It had off, medium, and firm. I don't remember who made it, it connected to the PCM wiring and it worked by fooling the PCM into thinking the car was WOT, which ups the pressure and gets firmer shifts. It worked ok.

Thanks, but I am looking for information of the systems that control all the operations of the auto Transmission (ie, Painless, PCS, GM performance parts, TCI/Fast)

Thanks anyway

I here people say the TCI controller seems to work well , Never used on myself though
