What Transmission is this?
My 86 transmission was starting to go out on me so I picked up a supposed 85 GSL transmission from the junkyard. I am thinking that this thing is NOT out of an 85 though.
60 mph is 3100 RPM and I am on stock wheels and stock rear end. I want to think I saw that it should be 2800. Am I just crazy?

SO, I have an 84 GSL that was an automatic. A good friend was parting out a 86 and gave me a transmission for free. I swapped over the tailshaft and converted the car to manual.
