6l80 transmission
Worked great for my 6l80 2007 escalade. First hole i did i came out with a crease in it lucky i had extra ones. The best way for me was to insert them like if you had a bowl upside down & just go around pushing it down. Watch

Price was right
Amazon was $60 cheaper than my local parts store. I couldn’t go wrong. Shipping took about four days and install took about seven hours.

Great Kit
This really helped improve the shifting on my 2015 Chevrolet Impala Limited LTZ. I checked the RPO codes in the trunk of the car to verify that I had a Generation 1 6t70 transmission. The kit was relatively easy to install. It took the better part of an afternoon.

Saved big money considering the alternative
Worked perfectly for my GM 6T70 trans. If purchasing be sure to buy the installation tool kit. Can't say enough about Sonnax for coming up with this. Worked like a charm. Kudos....big time.

Great kit
The tcm was priced at 896.00 at the local auto parts store. This kit fixed my tcm for pennies on the dollar

OEM or better.
It is the equivalent of oem if not better. Fixed my issue that I was having on my 6l80 transmission from my Escalade.
