second gear grinding

aceplayer25 · 01-23-2004, 09:33 PM

I have a 97 cobra with the T-45 trans. I noticed when I take off in 1st gear,run it up anywhere around 6000rpm, not speed shifting but just normally putting in 2nd gear it grinds. It seems like I read somewhere about people having this problem and changed the transmission fluid to a different kind that it helped the problem. Has anyone heard of this? I bought it from an old man a couple of months ago with 33000 miles and stored in his garage most of the time, it still had the FACTORY (dry-rotted tires) on it.This car has not been abused. I just purchased 3.73 gears and Tri-ax shifter that I will be putting in next weekend and would like to solve this problem before I do these installations. Thanks for reading, hope someone has some answers.

I had a friend with a similar problem and when he installed his new shifter it seemed to help minimize the grinding sound greatly.
Install your new shifter and see if it helps, before changing the trans fluid.

The Tri-Ax shifter is awesome. I could not believe the difference that it made. It may help with your problem by making the shifting more precise especially if the stops have gotten worn on the old shifter.

One thing to note, though, the after market shifters are noisier since they do not have any rubber bushings. You tend to hear a little more noise with the Tri-Ax. It is much more solid, precise, and the gears snap into place. It is a much more rigid setup so vibrations are more easily transfered.

Sounds like you found a real gem of a car. Wow! '97 Cobra with 33k! That is great. Good Luck.

Try a good synthetic trans fluid. I used to have a '92 Eclipse Turbo (before I became saved and bought American) and it did the same thing after about 35K. Better tranny fluid fixed it.

when you put the new shifter in change the trans fluid to royal purple it will help with the grinding as well
