Mr. Shi

The 2013 model year can be a Gen 1 or a Gen 2 Transmission.

Not sure what belongs in your 2013? Check the glove box for the list of

RPO codes. MHM, M7U, M7V, M7W, or M7X are listed as Gen 2.

Be Careful! As of 2/5/19, we have found models* up to 2016 that are sll

Gen1. They have RPO codes of MH2 or MH4. There may be others.

All 6T70’s: The vehicle, the TEHCM type and the Transmission version are

matched for Generaon and Programming. Do not cross-mix them.

Main Body Repairs (Front Side) = 10 Check balls Step 1. Remove and discard original Isolator retainer, plug, valve and spring. Locate New Relief bushing. Insert New .250 ball first, then New Blue spring into relief bushing. Now insert relief assembly into VB Isolator bore. Insert bushing far enough to install new spring retainer into outer groove of bushing. Trans is now protected from overboost cross leaks! Protects expensive hard parts!

Main Body Repairs Continued (Front Side) = 10 Check balls Step 1 Manual Discard original TCC Regulator Valve and spring. Clean the New TCC Regulator Valve provided and test fit it into the clean VB bore. If it moves freely, remove it and put a small dab of assembly gel into the groove of the new valve followed by the NEW Scarf Cut Ring. Now roll the small O-ring provided on top of the scarf cut ring and place it in the freezer for 15 minutes. This will “size” the ring into the groove.

Read This First: Due to the new vent location in a Gen 2 Rear body and the amount of bore wear seen, the AFL leak can not be fixed with a “drop-In” solution for the Gen 2 Actuator Feed Limit Valve. To repair the AFL Valve bore a tool kit is also required: TransGo # AFL-G2-TK Tool kit Gen 1 Rear body has No Exhaust here Gen 2 Rear body has Exhaust here Rear Body ID and Repair TransGo ® # AFL-G2-TK Tool Kit.
