Quoted from Gryszzz:
FFS please tell me there wasn't a Shelby Dodge Omni.
Every Dodge I've ever owned the transmission fell out. And that's like, 5 transmissions.
I'm afraid to ask what those were!
I'm not sure about the early model turbos, but by late 80s they were installing German-built Getrag transmissions specifically designed for the turbo engine with specially heat-treated and high-strength parts. Most impressive was the differential case with four-pinion design, good for aggressive launches. Likewise with the clutches, over-sized 230mm, 230mm pressure plate pattern, 8-bolt crank.
I only have good things to say about the 555 Getrag my car had, and I drove it hard: original clutch lasted over 100,000 miles. Shifted real smooth too, man did that clutch kick-back hard though, never encountered another car with a clutch requiring that much force.
