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.

Step 1
Discard original TCC Regulator Valve and spring. Clean the New TCC Regulator Valve
provided and test t 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. Note:
The O-ring is only used as a sizing tool.
To install, roll the O-ring o the valve and set it aside. Insert the NEW Orange Spring
into the hollow end of the new valve and insert new valve and spring into the bore
while it’s sll cold, followed by the original Shi Slug, End Plug and Retainer. It will
go right in if the outer diameter of the ring is ush with the new valve.
Never force the valve in. Once you install the valve and ring– DO NOT REMOVE IT!

Read This First:
Due to the new vent locaon in a Gen 2 Rear body and the amount of
bore wear seen, the AFL leak can not be xed with a “drop-In” soluon
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

Drop in sleeves work great on

Step 2. Aer reaming, clean the bore and the new AFL Valve
furnished in this kit. Make sure the valve is free in the bore.
Install the New AFL Valve and reuse original spring and retainer.
Tool Kit ts 3 dierent transmissions, just use the correct reamer guide.
Fits All Gen 2 Vb’s 6F35’s, 6T40’s and 6T70’s.
Step 1. The 6T70 Gen 2 uses the “No Groove” reamer guide.
Place the no groove guide into the bore ll it stops, with the
stepped end out as shown. Use lots of WD-40 and low speed on
your favorite portable drill, let the reamer do the cung unl it
booms in the bore. Don’t force the reamer, bore nish and
Reamer life require a slow inward movement and lots of WD 40.
