Comprehensive Kit for Big Problems You Don't Want Back
Knowing exactly what parts to replace in troublesome transmissions is an ever-increasing challenge, but Sonnax Sure Cure kits solve this problem for you. Each kit is a comprehensive reconditioning package featuring the best Sonnax products developed to help rebuilders restore and enhance transmission performance.
Restore Shift Quality & Reduce Comebacks
Each Sure Cure kit comes with the same Sonnax parts sold individually to resolve common valve body complaints as well as other transmission problems.
Easy to Use
Sure Cure kits include comprehensive, step-by-step installation instructions covering the inspection and repair of the most critical valve body areas.
Save Time & Money
Get everything you need for restoring troublesome units in one place, at one cost. Plus - no worries about comebacks! The high-quality parts in each Sure Cure kit repair worn areas and protect the transmission against future damage.
Comes with everything. So instead of 15 things on the wall, I have one box on the shelf. Best shifting 604's I've built. Period. The Sure Cure kits are consistent.

I do 8-10 units and use five or six Sure Cure kits a week and none of them have come back. Customers say their cars haven't shifted that well since they've owned it; they're very impressed.

I don't know how the hell I've built transmissions before. With the Sure Cure kits, you order one part number and you have all the parts you need.
