    Default T5 Gear Whine

    I swapped my AOD out for a T5 this weekend, and I've got some pretty serious whining through gears 1-3. 1st gear whines the loudest, 2nd is a little quieter, and 3rd is a little quieter still, but still way too loud to be considered normal. 4th and 5th are silent. It gets louder when I accelerate, and gets quieter when I coast. The noise goes away completely when I push in the clutch pedal. Also, it pops out of reverse, no clue what to do about that. It's infuriating trying to back up though. I filled it with generic ATF, a bit over 2 quarts. I'm using a Ford 10.5 inch flywheel, an OEM (parts store) clutch, and Maximum Motorsports clutch cable, quadrant, and firewall adjuster. All forward gears engage and disengage smoothly, or at least I think they do. They don't grind at all as long as I push the clutch in all the way. This is the first time I've ever driven a manual car. I can make a video if it helps, what do you guys think? Thanks!

    Possible issue, I didn't grease the input shaft bearing retainer. Could the throw out bearing make noise?

    No, it only has load on it when the clutch is pushed (i think..?).

    Might be a worn input shaft bearing. It's on the input shaft, behind the round cover that the input protrudes through. If you take the trans out to replace it (which is easy, the hard part is removing the trans lol) also slap on a steel bearing retainer. that will also give a better feel to shifts and last longer than the stock aluminum piece.

    They're going to make a little noise, but it shouldn't be audible at highway speeds.

    Also, you don't have your clutch cable too tight or not tight enough? Reverse is unsynchronized, expect some slight issues with putting the shifter into reverse unless you first shift into 5th. That slows down the spinning inside enough to overcome the non-syncing gears. Since it pops out of reverse, my guess is that the clutch cable isn't quite adjusted properly.

    That's certainly possible. I'll have to take a close look at it this weekend (got 4 days off ). I ran into an issue using the firewall adjuster and my stock brake booster, I'm not able to unscrew the firewall adjuster all the way. I was planning circumventing that by adding a bushing or two on the cable at the quadrant.

    I've heard this one before from my friend with a VR6 GTI. He started describing exactly the same issue moments after we installed a poly trans mount bushing to replace his blown out rubber one.

    Your helpfulness in helping the OP with his issue is only surpassed by your grammar.

    or, you're NOT driving a time bomb?...

    I would just pick up another tranny if I were you. Tom is probably right and It's not worth fixing unless you were planning on doing a build for more torque capacity. Was there any play in the input shaft before you installed it?

    T-5 noise in 1st, 2nd & 3rd is usually roughness on the end of the mainshaft that fits into the rollers in the back of the input shaft...

    Jumping out of reverse is likely a shifter issue(inside top of case) 5-R lever problem or maybe a chewed up reverse slider...

    If the mainshaft is bad it will require total disassemble to replace...

    Hate to say it but sounds like you have a trans that's taken a beating, any idea if it's a World Class('85-up) or std version???
