Looking for a Few Sonnax seals for their smart tech 10 disc high gear drum. I ordered some through my local Sonnax dealer but they won’t ship until after February 4th so trying to see if anybody has them in stock so I can get my trans back together.

Need:
Inner piston seal Sonnax part number 28756-07
Smart tech ratio style servo seal kit 28821-10SK

When I did my glide in my Corvette we ordered all my Sonnax parts from Summit Pro shop. Which they had all my parts in stock including my Smart-Tech Ratio-Servo Kit.

IHRA ACDELCO Canadian Nationals

SDPC 582 Head Hunter on methanol

i have found some of their stuff on ebay and amazon

Between Summit and Jegs I have been able to get any Sonnax parts I have needed. Go to the Sonnax site and get the part number you want and search that number on both Jegs and Summit sites

Yea tried summit and Jegs, can’t get either one from either of them. They have the ones for the standard 10 disc drum but not the smart tech unfortunately.

Try Hutch!

If Hutch can’t help try TSR in New Hampshire have been very helpful
