    200 4R and activation on a chassis Dyno

    One guy suggested letting the cable out a little but I was afraid to burn up something. Did you do this 2nd to 3rd shift at WOT then? How did he time recording, just wait for the shift?

    200 4R and activation on a chassis Dyno

    I come to you guys for this. How do you trick your 200 4R trans into staying in 3rd for a dyno pull. I went this week with my 455 Olds and 200 4R trans. The technician had to start at a higher RPM to keep it from downshifting and this caused lower HP numbers. I have a good idea that the...

    So what did you do? What did they find wrong?

    Simple or serious problem? 85 200 4R

    Looks like some of the problem was the clearance at the piston and servo. I ordered a larger servo and installed this weekend. Shifts were better than I have ever felt on this trans. I drove it around for about 30 minutes with no trouble. Then something changed for the worse. The car...

    0.500 boost and 0.400 reverse boost.

    Simple or serious problem? 85 200 4R

    The spring that came in the Transgo Kit. Aside from being low, it does not change after the trans starts acting up. I cut a seal a long time ago(now replaced) on the servo piston closest to the cover side. This caused a very weak shift to second. Could the pin to servo wear cause enough of a...

    Does anyone have any ideas on this trans issue now that pressures are posted?

    Simple or serious problem? 85 200 4R

    Sorry for the delay but finally found a working gauge and time to hook it all up, again. There are some round off errors in these measurements as I was driving and reading at the same time. They should give you a pretty good idea of what was going on. Pressure rise was instantaneous on throttle...

    Simple or serious problem? 85 200 4R

    Thanks for your descriptions here but my car really is a mild 455. Less than 9 to 1 compression and full exhaust. Most people claim thier grandmothers run bigger cams than what I chose. Maybe and I mean on a good day, 365 HP and maybe 425 lbFt of torque. I have not put any hard driving on this...

    Simple or serious problem? 85 200 4R

    I have a 200 4R in my 72 Cutlass 455 car (very mild). There have been a couple people here that have helped on getting my boost valves installed correctly and other thiings and I appreciate it. I have put about 500 miles on the car and I am noticing a trend that I am very concerned about. Here...

    Governor Spring failure

    I'm guessing that I need to address this pretty soon since I don't run a tach in the car. Thanks for the responses.

    Governor Spring failure

    I have seen a couple sites talk about needing a new governor spring because it gets thrown out of the governor. My question is what are the effects of this failure? What exactly happens to the car to see if this has happens? What is the faliure if the check ball in the governor sticks out of...

    Boost valve snap ring install question

    By no means am I an expert but maybe you weren't getting the PR all the way into the bore before the spring and valves. I used my pinky and made sure it went into the bore all the way before I started to install the springs and valves. Glad you did get yours done but on mine I am trying to do...

    Boost valve snap ring install question

    I did get a chance to drive it this weekend. There are a lot of things seem to be better but I have to get more seat time. I reset the TV cable before the drive and I think I need one more click tighter to be happy. Car drives very well like it is but I know it can drive better. One tip...

    Boost valve snap ring install question

    Mikestertwo and Luke, I slid the boost valve higher and got the snap ring in the groove. I think the play is probably less than 1/8 inch but the ring is truly seated in the groove. I finished putting the pan back on and filled the fluid back to level. So far, it takes gear really well both...
