Just wanted to tell you how happy I am with my Tranzilla. I’ve had it in the car and on the road for a few months now. It shifts so much better than the stock viper T56. I took it to a 1/2 mile event last weekend and never missed a single shift! 182.48mph in the 1/2 mile from a standing start. Chad A.

Thank you very much! for taking your valuable time confirming my S6 40 was in fact a simple oversight solving a VE issue… using a saved automatic option bin… the selected automatic switch table… did in fact lock out all gear selections energizing the solonoid except 4th… on the ZF manual… saving me time and aggravation.

The new trans is working flawlessly. Just did a 192 mph in the standing half mile. Also did 1280rwhp and 1300rwtq on our mustang dyno. Only running this power level at the event.. but its shifting very nicely. Joshua K.

Rockland Standard Gear’s Tranzilla Magnum 6-speed gearbox played a key role in setting the NASA ST2 track record at Pitt Race, and helped me win my past SCCA Kryder Regional and V8 Stock Car North GT-1 championships. The shift quality and reliability are just amazing. Thanks Rockland! Chris D.

THANK YOU!! for your advice last week with my Tremec (TKO600) issue (stuck in gear). I did what you said and removed the reverse switch. I was able to see the 'lever' inside...eventually (with car on lift) gave the rear tire a good budge, ...and bingo if freed up!! Now able to go through the gears and hit neutral just fine. You saved me from having to drop the trans out of the car... : ) Kevin K.

Your T-6060 is the smoothest shifting transmission I have ever had in ANY car I have ever driven. I am very glad I decided to spend the extra money to buy one of your new gear boxes. MONEY VERY WELL SPENT. Steve L., National Champion

I just wanted to thank you for the quick turn-around. Got the trans on Friday and installed it Saturday. Looks like I'll be making my next event. Thanks for the excellent customer service! Doug
