Give us a call and talk to TJ. He can answer all your pricing questions and let you know what will work great with your combination.

 

I've talked to both DTE & TJ at RPM. I'll go with RPM since i get the same rib style as i send them. DTE only gives you a 3 rib diff back if you order a stg 3 or 4 but not 2.

Anyway, i want to go with the RPM stg 2 but i'm worried my good tires and power will bust those C6 Z06 output shafts with what i call a good launch lol - even though the C6 Z06 is 505hp. Am i crazy?

Thanks!

 

u cant go wrong with either company, and if u have a problem with either then will both be there for u!! so no worries.. as far as c6z shafts i would think your gonna spend as much on those as you would of the hardened shafts

 

You can't go wrong with Rodney and RPM Transmission:

 

Here is my 4L65E Stage VI with a new 3.42 3-rib, Level 3 Diff, all from RPM!

 

DTE for me. I have the stage 4. Never broke and and never makes noise. Jenny and Phil are great to do business with. I will be back to DTE and now they can help out my BWM!

 

Good thread and we'd like to chime in as a point of clarification to some inaccurate information presented.

Good one here... Dynotech Engineering Inc./DTE powertrain Inc. has been in business for nearly 10 years and LONG before the existance of "RPM". Check online public business records of each enterprise to confirm for yourself if you wish and we first met Rodney when he was working at tiny a mom & pop transmission repair shop in New Castle, IN. in or about 2002 or 2003. ("mom and pop" meaning repairing mom & pop type everyday, passenger car transmission repair) Over the years, we have introduced many pioneering product designs and build techniques to the Corvette driveline that have become widely accepted and copied practices as standard across the industry today. No one "taught us" anything about differential or transmission building, as we sorted it out ourselves over the years. Give us a call if you'd like the complete history timeline of everything and we'd be glad to enlighten you.


We love how some of the above differential photos from our competition are built with our parts or at least direct copies of them i.e. differential strut, billet aluminun side cover, etc. All good.


Incorrect and sorry for the confusion. When a Stage 1 or 2 differential is ordered from us, we also send the same type of differential design that is shipped back to us, however, the customer has to confirm what he has in the car for us to build him a duplicate design differential. The Stage 3 and 4 racing differentials are already built upon HD castings and that is the customer receives regardless of what he sends back, hence the price difference for the heavier duty models that are designed with rigorous racing in mind.

No worries though and we're glad you found something you liked with whom-ever you've chosen. Good luck with your purchase and have a great day!

RPM !!!!! THE FASTEST CARS !! #1 IN CUSTOMER SERVICE !!THE BEST DRIVE LINE SOURCE!! MOM AND POP MUST OF TAUGHT YOU WELL !!

 

A brief history of me and RPM. When I graduated college with a degree and my A&P licence (FAA Airframe and Powerplant) I worked for 3 short years at Mt. Comfort airport as an A&P while all along building transmissions at home. In 1996 I started my own (not worked at) transmission shop called Transmission Specialists with one of my best friends (and still is) and sucessfully ran it until 2004. I then left the partnership and started RPM and specialized in high performance transmissions only. I started at the bottom and have built this business with a lot of hard work and great employees (no loans,investors,etc....) RPM has grown to 8 full time employees with a few coming with me from the old shop. I don't believe I have ever been a mom and pop transmission shop. (will some one please define mom&pop for me?)

"DTE learned from working with RPM"

The above quote from a post is incorrect.

 

Sure and my post is fixed above to reflect what was meant. You and I have spoken about this before many, many years ago, so it was assumed you knew the industry terminology, however, the further clarification was approprietely applied. Have a great day!

We do not care to sell diffs outright so by all means please go that route! However, we have been building C5 diffs since before the tools were available to the public from Getrag, we have literally 100's and 100's of builds under our belt, with to many feathers in the cap to start listing in regards to race wins with our products or built rears.

I do not personally know of another N.E. shop that you can schedule a day and wait for your rear swap, and watch it being built if you wish, then be back on the road in a few hours. This is the way it has always been here at ECS, and we do not plan on changing now.

If we did not build our own diffs though, RPM would get the call from us.

 

Funny, the story is nearly the same, with the exception of building race engines at home instead of tranny's.

 

Those of you that know my 2000 C5 Coupe warmly nick named the "Barbie Vette" know that I have worked closely with DTE, RPM,FLP, ECS, and FLT over the years.

All these shops have played a significant roll in the progress of High Performance Corvettes over the years.

My 1,000 HP Street Legal Corvette was running 9.20's @ 152MPH last year with 60' times between 1.39 and 1.45 off the foot break, with Slicks 10" Wide.

I currently run a Rear End Assembly from Rodney because DTE could not keep up with horsepower much over 750. May not be Phils fault, but he chose the gear sets that failed numerous times back in 2007 and Rodney stepped up to solve my problem and I have been running the RPM setup for 2 years now without any problems.

I have no "axe" to grind and am a "results" oriented guy. In 2010 Finish Line Performance will be "stepping up" my setup a bit and Rodney (RPM) will be playing a significant role in my success. I can't think of better shops than ECS, FLP, FLT, and RPM to have on your team if you are out Drag Racing in the 8 or 9 second range. These guys will GO TO THE END OF THE EARTH FOR YOU and keep your car in the competition.

Just follow their advice because they know what their talking about when it comes to High Performance Corvettes!!

Rodney & his crew @ RPM are great.
Couldn't ask for better service.

 

So you're saying you never built a transmission for a minivan except that one that ran a low 11 second quarter mile?

 

Exactly right!!!! RPM has built me a great (and durable) drivetrain to run 1.30 60' times and 9.5@142 in a N/A C5. RPMs quality of workmanship and outstanding customer service is what sets them apart.

 

We get a lot of calls for mail order diffs and RPM is the only shop we recommend time and time again..

 

Two pictures to show you guys the BEFORE and AFTER of RPM's work:


BEFORE



AFTER




The time frame difference between the BEFORE and AFTER pictures is approximately 4 HOURS.

 

I usally never get in here and bad mouth anybody been a member here for a long time worked with many a vendor on here but I can tell u from first hand exp I would never let DTE touch my car again what a joke. Ive been threw 3 DTE rears and I was even dumb enough to let hem keep my car to go threw it make it safe get my N2o to working right and he was going to get me faster well 14,000 dollars yes 14,000 dollars he brings my car to the track cause we were doing a pinks show hell my cars 3 tenths slower and now my N2o not working right and all Phill can say is it was working when I left the shop so now I at the drag strip working on my car does he help no but A guy from another shop helped me. We get my car back to another shop and get the tune fixed that he put on there another Joke so If u want to spend a bunch of money and go slower GO to Dte and I will be glad to post the bills for everbody see what a joke it was dealing with DTE A 14,000 dollar joke. Oh yeah the only time anything I got from rpm broke Is when my wonderfull $5,000 DTE rear end would brake and lock up which was about 3 times
