Replace the weak, vulnerable transmission intermediate plate on your vehicle to extend the life of your transmission. Your stock magnesium intermediate plate wears out and will often crack after years of use. It’s also one of the first and most expensive parts to fail when you increase the power of your engine. Precision machined from extra strength 6061-T6 aluminum, our bullet-proof plate is the solution for tired transmissions and has passed road and track tests in 911s powered by over 300 horsepower engines. Bullet-proof intermediate plates fit all 911 and 912 late 1968-71 with magnesium transmission case only. For stock or hopped-up engines, V6 or V8 engine conversions, our bullet-proof intermediate transmission plate provides the many thousands of care-free miles you expect from a newly rebuilt transmission, yet saves you money over a new standard intermediate plate.
