200R4 Swap ? - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Big thing I noticed was the view looking down around the motor to the ground with the hood up. The 2004R is a lot narrower than the TH350.

Got mine mounted up and bolted in the rear position. Drive shaft is a bit further into the trans then I want....but then again I haven't got the rear end exactly where it needs to be.

oh....and I came across this diagram of a 200-4r the other day.

current drive shaft position:

I've had one in my 67 for a couple years now. The only issue I have is that it won't kick down out of lock up until there's a lot of throttle (or tap the brakes but it goes right back into 4th). It's a pain when in 30-45mph traffic as it lugs the motor. I've been to 3 tranny shops for adjustments but it hasn't worked out.
My solution was to put in a small dash toggle switch connected to the brake switch sensor and switch off the lock out when cruising around town (back to basically a turbo 350).
Do you guys have any problem with it releasing 4th gear lock up at a reasonable throttle position? Maybe I should continue my search for a tranny swap expert.

I only use the lockup over 60mph.

I am looking to put a 200 r4 behind a chevy 250 3 speed also and was wondering what flexplate and torque converter you are using?
Thanks

I would also like more info on installing a 200-4r behind a 250 I6, has anyone done more research since 2010?
