01 gt transmission problems-help needed

[tmqdoc]

01 GT 5-speed 75,000 miles
TR3650 transmission
Steeda triax shifter

My problem:
This morning ,while driving to work, I noticed a grinding noise when shifting from 3rd to 4th. I didn't think much of it and thought I was probably just not engaging the clutch all the way or was not in synch with the clutch when shifting. However, it did it again. After work, it continued. It would not do this if I shifted very slowly.

It has never done this before. I change the tranny fluid with synthetic mobil 1 every 12-15K. I installed the triax shifter 3yrs ago and have had no real problems with it.

Anyone have any ideas?

Thanks for any help,

Chris.

I think this is a pretty clear sign that your synchros are worn out.

What's a fair price to have that repaired if that is all that is wrong?
