Ever since ive owned it, it grinds when I put it in reverse. It shifts perfectly through 1-5, but 2 out of 3 times it grinds going into reverse. Its rather embarrassing, any ideas? Tranny going bad or linkage?

Completely normal. Shift into another gear whilevthe car is in neutral and then slide it into reverse.

Mine does the same thing. This suggestion works for me pretty much every time.

My 96 Cobra used to do that all the time. If I rolled up an inch in 1st gear then switched to reverse it was fine....or if I stuck it in 5th, then went to reverse it would be fine.

Your reverse synchro is going bad tho. I eventually replaced mine because it got to the point where it wouldn't go in at all. I would pull with all my might and couldn't get it into reverse. It was crazy.

I'm not familiar with the T45, but the T5 does not have a synchronized reverse gear. Thus, grinding noises going into reverse are very common, and happens when the car is not completely stationary or the guts are still spinning freely.

Like said above, shifting into any forward gear with the car sitting still stops the internals from spinning and eliminates the grinding sound when going into reverse (assuming you keep the clutch held in). Also, jamming the lever into reverse like you're making the trans your bitch helps, too. You get in the habit of doing this and it will never grind.

Up into 5th first, then into reverse. The grinding will disappear.

"if you cant find 'em, grind 'em"

yelling that out the window before attempting to shift into reverse should help relieve the embarassment

I'm not sure if it's a synchrod gear or not either...I know the new on at the dealer was pretty expensive and my trans shop put it in for me. My other one had excessive wear on the edges...didn't look too bad, but they said it was enough to give me problems because almost all of the teeth had it.

As stated, shift into 5th gear and then shift into reverse.

No more grinding.

If it still grinds, then you better have it looked at.

Mine likes to slip out of reverse unless I hold it in gear. The first time it banged out of gear I thought I hit another car or something, it was LOUD!

Could be a lot of things. Worn sycros/blocker rings, excessive countershaft endplay, if you've got an aftermarket shifter, it could be as simple as your shift stops not being adjusted correctly.

I actually never looked into it that closely. I probably should, but I don't spend that much time in reverse and I barely drive the car these days :0
