Part No. 44912-08K

    Tooling: F-44912-TL8,  VB-FIX (not Included)

Vehicles with listed Chrysler transmissions often show up in the shop with TCC related troubles. These concerns may include trouble codes accompanied by TCC slip, no lockup, overheating and loss of fuel economy. In some cases, the TCC may be unable to release, resulting in improper lockup and engine stall.

Problems such as these are often caused by excess wear in the TCC switch valve bore, which allows vital control pressure to escape the circuit. Reconditioning the bore and installing Sonnax oversized TCC switch valve kit 44912-08K restores crucial clearances for renewed TCC control and operation.
