1Cobrat You are not the first to have the same problem. I went through this in 97 with the new 6spd that came to market. My car wouldn't shift over 2,800 rpms with clutch, I could bang it into gears by coasting, letting the rpm's drop and slide into the next gear. I don't know what clutch you have but, IMO the centerforce gold SUCKS. Centerforce was call 6 times and NOBODY in TECH know what they are talking about. I sent the trans back to Richmond thinking it was a trans or shifter problem. They call and said no problem. I explained the issue and they had it put in someones car and driven for a couple of days, Again no problem. It was sent back with the shifter setup by them. Put the trans in the car and the same problem. Call Centerforce and went round and round about those sliding wieghts and how they work. Centeforce SWORE it was the TRANS. I was not into racing but was heading in that direction. So I got a new G-Force clutchless 5 spd and 2 shifters for the trans. $6,500.00 dollars later and 2 weeks the new trans was in the car. Same shifting problem over 2,800 RPM. The bottom line is the weights are locking up the disc, unless you have a heavy TOB and strong fork, you will bend the fork and the clutch will not RELEASE. I pulled the trans and ripped off the weights, reinstalled the 5 spd and no trouble shifting at 6,000 rpms, put 6spd in car and no shifting problem at 6,000 rpms. PI$$OFF person. I have been racing with both transmissions since 98. After running roadracing, my trans starts to get stiff shifting. I run 85W-90 synthestic. I gets very hot in the tunnel araea from no way to remove the heat from the inner brakes and heat from the motor. Was given 3 ideas, Change the fluid to
Amsoil rearend lube, Go to ATF fluids( all the new cars are running ATF instead of heavy gear fluids ), or add a trans cooler and pump assembly to the car to keep down the trans fluid temp. I have double reflective tape on the tunnel for heat inside the car and my headers are rapped, and inner Jag brakes get hot from racing. Richmond sells GL-6 that is 75W-140. This almost the same stuff as what I am running. I am looking at the cooler idea. The ATF bothers me, I will need to call Richmond on this before trying it. My Trans binds up after 15-20 minutes of racing. Good Luck. I will reply after talking to Richmond again Rick L.
