tranny sound???

[mk3jetta-man]

i have a 92 cabriolet 5 spd and when i drive the tranny is really loud with a whine....it sounds like an rc car but its louder then the stock exhaust any one kno how to stop that sound

[s2kvondeutschland]

Fix your leaks and put some more oil in your transmission.

Or ignore it and destroy 5th.

[mk3jetta-man]

i dont really use fifth not may places here to lol but ill look in to the leaks .....how would i find them if i may ask

[briano1234]

Get under the car and look up.

The manual transmissions usually leak from:
Axle cups.
Front Seal.
Push rod seal.
Rear tin cover.
Speedometer Cable seal.

Usually the leaks if not really bad will not drip as most of the leaks drip or leak on moving components and get sprayed on the underbelly.

whats a good fluid to use after i check all of this

[dave93cab]

GM Synchromesh seemed to be the concensus when I was looking to do mine. I am still dripping, need to look at my speedo cable gasket again. Sorry to threadjack, but does anyone use sealant on that seal?

[briano1234]

No, the gasket is cheap and effective.

[s2kvondeutschland]

Many people like synchromesh-type fluids, even though they are a bit thinner than spec'd for our transmissions.

I use Honda MTF II. Try, you'll like it. The one catch with it is a shorter OCI. I change the fluid every three oil changes or ~21k miles.

Yeah I installed a new gasket. I had to put a longer bolt in there to grab some threads, maybe the bolt was too long and it's not fully seated. I'll have a look. Sorry OP, threadjack over!

thanks guys

where did u find the gasket and bolt

[tolusina]

Is the noise this car makes maybe a wheel bearing??

[mk3jetta-man]

no i kno the sound of a wheel bearing cuz that just started to go this sound is deff from the tranny cuz it started after i changed the tranny awile ago

[rabbitnothopper]

wheel bearings sound like grinding rocks at warp speed

transmission bearings sound like whining (differential)

the bolt is M7x 1.25

transmissions leak, even after you replace all the seals

while everyone recommends Synchromesh...i tried it once
drained it out a week later and dumped the oil
went back to 75w90....
Synchromesh is too light, it leaks more, and whines more
if you have failing synchro rings it will help aid shifting (band-aid)
if you have failing input/output/differential bearings only things to fix that is replace the bearings inside the trans

[dave93cab]

Is there a significant difference in thickness/leaks between the two?

I'm tempted to try a different oil. I have no strange sounds from my transmission, but no idea how much i have leaked out, so might drain and re-fill when I investigate.

where did u find the gasket and bolt

GermanAutoParts.com, I found my email receipt but can't find it on their site anymore, bolt from Lowes!

[dave93cab]

the bolt is M7x 1.25

Can't find any M7x1.25 bolts anywhere! Any ideas on where to get one? Also, do you happen to know how long it is? Thanks!

I just put in a new speedo cable two days ago and couldn't get it to seat properly with the gasket... I wasn't getting any speed readings at all. Without the gasket it seated just fine and I could finally tell how fast I was going. As long as I pay attention to fluids that shouldn't be a problem, right? It seemed like the metal cup of the cable was pressure fit into the hole in the transmission, quite perfectly.

Might have solved it (the speedo gasket bolt)

N0901733 is original part number, called a local dealer said no-one around has one

It has been replaced by

N90009201 (Bolt)
N0122345 (Washer)

Spec is M7x1.25x13mm

I'm going to try to order one but I have the feeling I need one a little longer as I think the first few threads have gone in my tranny.

[dave93cab]

how about a helicoil kit and be done with it? Anyone have experience with these?

Can get M8x1.25 bolts everywhere

dont do it, you'll have metal in your transmission

i can get M7x1.00 easy but the M7x1.25 arent easy to come by

been meaning to order some from fastenal or one of the other bolt/hardware companies
oh, snap-on...that company

I called my local fastenal yesterday and no luck from them. I'm going to have a good look at the position of the hole tonight and decide if there's a way I can drill with surgical precision and seal the area up while i'm doing it.

The drip I have is annoying as hell, I can't park my car outside because it fouls up the paving. Gonna have to drain and fill the tranny again too. I'll probably switch to some 75w90 if it is less prone to leaking. Haven't been driving my cabby much, I want this solved once and for all

[mk3jetta-man]

ya i kno how u feel about the leaking on the pavement....i also have a slow drip in my oilpan from the drain plug i gatta get a new pan one of these days
