Solenoid codes are only repairable on TCMs with part numbers ending in "7332." If you have any other part number, we can not repair your module for solenoid codes. Part number is stamped on the back of the TCM and can also be viewed using a diagnostic scan tool. Solenoids and wiring harness must be tested for possible failure or short.

Part Numbers: A0002701700, A0002702600, A0002703500, A0002703400, A0034460310, A0335457332, A0335456732, A0335456632

It is your mechanic's responsibility to pinpoint the problem to the TCM. Do not send "replacement" or "salvage yard" units, as SCN coding is required. Do not send the Valve Body itself, doing so will increase return shipping cost. If you or someone else tried to repair your module, we can evaluate and possibly repair it, but only in the case that no additional damage was created. Please note, not all modules are repairable.

The repairs made to your moudle are covered by our Limited Lifetime Warranty. Please read full warranty terms and conditions.

After installation history trouble code/s recorded must be erased using original STAR tester or equivalent, like Auto Logic, Launch or properly updated Snap On scanner from ECM and TCM, otherwise code/s will remain in the system and keep the vehicle in "limp mode." 

After our repairs have been made, your module will be ready to install back on your vehicle, no coding or programming required.
