Gear Lube T-5 Question

Hate to ask - is this noise/vibration coming from the 1st used tranny, or the second used tranny? (ref: your other post about the bill)

Doubtful that type of fluid would cause the problem; there are no different 'weights' available in atf that I'm aware of.

I'll certainly second that. I don't believe there are different weights of ATF, and if its red, odds are that it IS ATF. So sadly, I can also give you a pretty good guess that the sounds aren't being caused by your fluid.
 
So, you're only getting the noises and vibrations at high rpms right? My transmission has been doing the same thing for a couple of years now. It's just a little worse since I got the 3.73s put in. Have you checked your transmission mount for cracks, wear, rips?

yea only at high rpms. well thats kinda good news that youve had that for a year. have you actually looked inside your tranny for any problems or have you just ran with it?

I've just ran it, lol. I thought it was probably the driveshaft for the longest time, so when I had my 3.73's put in I also put in an aluminum driveshaft.....didn't fix it. I just put in a polyurethane tranny mount a couple of days ago, but I haven't really tested it because my car has a miss in it right now that I have to fix.
