Propulsive Dynamics, LLC is happy to announce that we are now offering a complete drop-in solution for the 6HP21/19 transmissions that are currently found in N54/N55 powered vehicles. It is preferred that the customer send in their stock unit for rebuild, however, sending a salvaged donor unit is also possible. It is of note that vehicle models 2009 and up could need a ECS module reset via NCS Expert/WinKFP to reactivate the paddle shifters after install.
We also strongly advise that the end user utilize an ATF cooler to aide in heat management of the system that uses true AN fittings. The use of AN fittings is important due the increases in ATF pump pressure and volumetric flow-rate.
The fully built transmissions offered by Propulsive Dynamics feature the following…
- Upgraded G3 Friction Material frictions
- Upgraded Kolene steels
- Increased clutch plate counts throughout
- Upgraded Race Bushings throughout
- Complete Overhaul Kit by ZF
- Fully rebuilt and upgraded valve-body
- Fully rebuilt and upgraded torque converter (stock stall, currently)
- Each finished unit is fully calibrated on a loaded transmission dyno cell
- Each unit is shipped with a calibration data packet which also includes the adaptation procedure
Propulsive Dynamics, LLC has formed an exclusive partnership with European Transmissions. They will be performing the rebuilds and dyno calibration of all of our units. They are a BMW certified transmission refurbishment facility for BMW USA.
The calibration procedure includes increasing line pressures in each clutch drum, increased flow through the ATF pump, adjustments to slip durations to compensate for the increased friction coefficient and adjustments to the adaptation parameters themselves in order for the system to learn within its new boundaries. We are rating the performance increase at ~30% over the known capacity limit of the stock configuration with increased spectrum of usage and margin of safety.
I wonder how many people are actually aware what a re-manufactured AT costs. Just a hint, it's more then what Jason is selling you an insanely (over) capable transmission for right now.... Any other AT guys out there that want more power now\or in the future, or just want a transmission that will last with the car, I highly suggest getting in on this boat, as it's about to set out.
Just waiting for one last guy to pay then we can get this rocket off the launchpad.
Just a note...I had a meeting with EuroTrans yesterday and they informed me that they have freight connections into Europe that have insanely low rates so I will be offering our transmissions to Europe as well.
For anyone interested, PM or email me for a freight quote to have it shipped to a hub near your location.
Easiest way to accomplish this is to find a lower mileage unit that closely matches your car production year from a vendor in the US and have it shipped to us. I did some digging today and a place called E&Y Auto Parts, LLC has low mileage units (this one had 67K on the clock) including TCC for around $550 shipped to EuroTrans, which is an absolutely incredible deal.
