200 4R Install Questions.

Thanks for the info. When I talked to Art year ago, he had just gotten his name back from the Chinese, or whomever. Told me that he could build a 200 or 700 to handle 1500hp. Got an after market TV cable n bracket. Will never use stock again! The torque converter lock-up is always the week link. I looked at the Extreme Automatic's Web site. They have someone build a converter with 3 carbon fiber pucks on the clutch. That's the way I'm going. Will dig deeper later. Manual lock-up in OD. I'm thinking that if I add a 150hp spray down the road, I'll be just above 800hp. So I'm building it to last.
On your's You should be able to feel the converter lock up, and RPM should drop, about 300 or so on the tach. When stepping on the gas it should unlock go up 300 ish RPM. I'd call Extreme. Was talking to a friend in the car club yesterday. Owns a transmission shop for 30 years. Called the 200R4 junk. Got to talk with someone in the know. I haven't called them yet. Will soon. Good luck


In stock form, with the exception of the Buick Grand National version, they were weak. Like with so many things though, with a little know-how, some heavy duty parts and lots of experience, the 200R4 is an incredible transmission with nearly perfect gear ratios, shifting characteristics, amazing reliability, high-efficiency, low parasitic drag, compact size and low weight. Nothing else even comes close for folks interested in updating their old Mopars. Now, with the availability of the bellhousing adapters, and functional lock-up converter features, its a win, win situation.
