Transmission - All issues resolved IPT

Alright, I know we all dont have 5K but if you got extended warranty I think your good. Check this out: http://www.importperformancetrans.com/bmwauto.shtml

This is a rebuild from IPT Transmission. With this, I'd recommend going Dinan complete including software, intake system (throttle body, intake, maf sensor), supercharger, and exhaust. You'll be looking at 450HP plus with a transmission ready to handle it all and put it down accordingly. Next is gonna be that sport-diff :P

Valve body is custom calibrated to provide the ultimate in clutch application power and clamping force. Clutch apply time is greatly reduced and inadequate, sluggish line pressure rise is totally eliminated (The valve body modifications performed by us are of a proprietary design and are unavailable elsewhere).

Hi Energy friction plates and IPT laser cut, surface treated 1008 steel plates are installed in all shifting clutches.

*NEW FEATURE* We have now developed the industry's only 7 friction disk "C" clutch pack, 6 friction disk "E" clutch pack and 6 friction disk "F" clutch pack for a tremendous increase in second, third, fourth and fifth gear holding capacity.

New one way clutches (sprags) are installed in all locations.

Upgraded Reverse Drum installed in all units

Planetary splines are heat treated to prevent stripping.

Cryogenic treatment is applied to input shaft and planetaries to eliminate stress related failure.

Sun shell is heat treated to prevent stripping.

Lube system is redesigned to provide increased flow and cooler operation

Lock up system is revised to improve converter clutch application, clamping force and torque holding capacity.

IPT's proprietary package of modifications represents the most robust and capable ZF automatic gearbox configuration available anywhere.
