I have been on the FI section of this forum for awhile and now that I have had IPT do a complete upgrade on my ZF auto, I am now getting transmission error lights which Buckhead Import Performance says has to do with the traction control. BIP says that they have not found anyone who programs the TCU (no, not even IPT) in order to fix this glitch. The car runs fine until I punch it to carry more speed thru a big sweeper, the transmission light comes on and it goes into a partial limp mode - shifts when it should but very hard, I turn it off, wait a minute and restart which clears it. Until I do any power acceleration with the car in a curve.
Who can I go to to fix this computer glitch in my TCU programming?
