Maximize 68RFE Overdrive Clutch Capacity & Squawk Resistance with the Sonnax Smart-Tech® Housing

When trucks with Chrysler 68RFE transmissions are pushed to the GVW limit - or even when small amounts of power are added - the Overdrive clutch quickly surfaces as the weak link. Clutch burnup and a squawk on the 3-4 shift both can be traced back to problems with the OE clutch. Rebuilt units are at even higher risk of squawk due to tuning mods and aggressive aftermarket clutches.
Watch this video to learn how to easily eliminate the root causes of all these problems with the Sonnax 68RFE Smart-Tech® Overdrive clutch housing kit. This all-in-one upgrade is packed with cutting-edge features for 20% more clutch capacity, improved shift action and outstanding protection against heat build-up.
Sonnax kit #72960-16K is the new, improved version of the original housing and features:
• Custom BorgWarner clutches for maximum capacity with state-of-the-art squawk resistance
• New, longer plate screws for extra secure fit and flange head for optimal clamping force

I know this is an old video but people are using single sided clutches in 68rfe transmissions in high horsepower stuff with this drum with no problems. Tuning is the key to making these live with added power.

So you have changed the clutch material from the original drum? The clutches that came with my Sonnax drum were dark gray if I remember right. I had the 3-4 squawk too but that seems to be better. I can't remember for sure but I think Sonnax tech support told me to add some lube gaurd the the trans fluid.

Yes, this new and improved kit features custom BorgWarner clutches optimized for max capacity and squawk resistance, plus longer, flange-head plate screws for extra secure fit and optimal clamping force. Thanks for reaching out, and have a great day!

Can this be used in conjunction with the TransGo High Pressure Tuneless™ Reprogramming Kit for even more holding power?
