Hi all
The folks over at Team Chevelle said you guys know 200-4rs better than anyone. I must admit I am a transmission dimwit, so I need all the help I can get. I just converted from a Powerglide in my 69 Chevelle. I picked up a 200-4r from a boneyard out of an 86 Buick Regal S, with a 307 V8. After breaking in the cam on my new engine (350, about 330 hp), I took it for a little spin around the block. Some problems came to light:
1. Very little reverse. Just enough to back it out of the garage and get it moving down the driveway. It slips like crazy if I give it any gas at all.
2. First gear is good, but it's very reluctant to shift into second.
3. I can get it to shift into second by lifting off the gas, but second gear slips like crazy.
4. I don't know about 3rd or 4th because I haven't gotten the car over 25 mph.
I changed the fluid and filter before I installed it. I also bought a TV Made EZ kit from Bowtie Overdrives for a Q-jet equipped car and changed the valve body spring as per the instructions. I also adjusted the TV cable per their instructions, then readjusted it after the first test drive.
I'm thinking the trans is toast, but I could use the opinions of those who are much more knowledgible than I. Should I perhaps pick up a pressure gauge and do some more checking or should I just go ahead and yank it? What might be causing the problem? If I replace it with a reman from, say, O'Reilly's for the same application (86 Buick), would that be sufficient or should I opt for something beefier? I want something that's going to stand up to the new engine but not something that's going to snap my neck when it shifts either.
Thanks for your help.
Cheers,
Andy
