First, I would like to say Hi. First time poster on these boards.
A little about my ride and my problem. While I do not own a GN, (Wish I did, got really embarrassed by one back in high school '88) I do still have my '70 Monte Carlo from high school that I am doing a body off rebuild/update. I have retro fitted my 350 to TPI from an 89 IROC and modified it to a Speed Density set-up with a 200-4R trans out of an '85 Monte SS. Future dreams include adding a pair of turbos.
Now my problem. I got the 200-4R already pulled from the junk yard from a wrecked MCSS. I pulled the pan and although the fluid was looking burnt everything I could see was very clean. The TV cable did not get removed before whoever pulled it and was cut after apparently hanging from it. Which broke a spring that helps to return it to it's normal position down by the valve body. I pulled that apart and modified the spring (Bent) so that it would hold the cable correctly and took my chances and installed the tranny. Now I finally got to test drive it a couple days ago for the first time in 16 years and when I put it in Reverse it goes forward like it's in 1st gear. I took it to the end of my court and back and everything else seemed ok. I had it up to about 35mph but never really felt any shifts. btw I have a 3:73 posi so I would think it would have shifted into second by that speed and I did have excessively high rpms so I'm sure it at least was in 2nd.
So Why is it going into low when Reverse is selected? I think, big think there that they both run off the same gear set and it just that in reverse the forward clutch pack is not engaged... Is there an easy fix? Time to just go ahead and pull it and rebuild? Maybe that plunger got stuck in the valve body?
Sorry I know it's a long post but I wanted to give as much detail as I could. I have verified the shifter linkage and the TV cable set-up too.
Thanks,
Steve
