1999 Volvo S70 Q&A
1999 Volvo S70 Question: tcm where is it?
If you're looking at the engine, on the left side you'll see a black box, the TCM is in this box. There are 2 metal clips that hold the top cover on, they are unclipped from the bottom. I think you'll need to program the new module, plus reset the shift adaptation to adapt the module to the transmission. To remove the module, pull up on the metal tab on top of the module. - Bret Bodas
autozone hooked up the check engine equipment and it said the tcm was bad causing the abs and brake lights to come on and drag. - Visitor
