I've had a GER "Thunderbolt" in my car (904 trans) for 18 years now - it must have been made the ONE WEEK they made a decent converter. Good street manners and 4000 stall when it needs to. My car has run consistant 11.30 at 120, with 1.50-1.55 60's for years with it - went 3 tenths slower with a $500+ 10" T/A converter in it. Now, I will say their customer service is non-existant. I cracked the pump drive - C/M snout wasn't avalible when ordered in 1994 - and sent it to them for a new one, since NOBODY else would touch it. Repair went from a quoted 3 weeks, to 7 weeks, to "we never got it". Well, UPS tracking showed they had signed for it, so then they "found" it and put it in the tail end of the repair line. Didn't even have the decency to put it at the front of the line. When I finally got it back, I will say it has been flawless and owes me nothing if it fails tomorrow. Which it may - next time out, it will see a 100 shot as a "how do ya like me now"
