Loud 1st gear

mattio781 · #1 12-03-2004, 10:39 PM

I got a 91 si with 151k on it, and my 1st gear is so loud, sounds like i got a bunch of hampsters having sex in it, also 2nd is kinda loud but tolerable, i just changed the oil in it 2 months ago and it got a little quieter, anybody else dealing with this or is it just me. I was also thinking of draining it again and running full synthetic to aid it, any help or answers....you know what to do

don't put in synthetic. it'll be bad for it. high miles and synthetic don't mix. does it grind going into gear? or just makes lotsa noise once in gear? any shavings or metal bits in the tranny fluid u drained out? how easily does it shift thru the gears? wut vicosity fluid did u put back in? sounds like u have gears that have been beaten to death in there. and the chipped teeth r making the noise. if u'r lucky it's just the syncros and those can be replaced pretty easily at a tranny shop. run by ur local tranny shop and see wut they say. but try to describe in excessive detail so u give them more info than they need to pin point it.

It's either gears, synchros, or internal bearings. Once the noise is there the damage is done, NO fluid will fix it. Time to replace the trans with a used or rebuilt unit. It's a total waste of time & money to try rebuiding your current trans. Parts & labor add up very quickly. 1 gear set alone is like $200 + 6hrs of labor to R&R the trans.

shifts great, no grinds or anything. i put 10w30 in it as thats what the manual said to put in it. The oil was dark as hell but no shavings or anything

the manual says 10w30 for tranny fluid?

edit: damn it does, thats really thin.

i just use pennzoil syncromesh fluid, does anyone know the viscosity and weight of that? it seems to work good.

stands for winter, as in cold.

about changing the fluid, you guys should really get the MTF (manual transmission fluid) from honda. ive tried all sorts of multigrade oils, conventional 10w30, syntec 10w30, mobil one 10w30, and even redline 10w30. none of them felt as good as the MTF from honda. i dont know what they put in it, or if its truly nothing special and just tricks me with its "genuine honda" label, but it works.

Dude its WEIGHT not winter

weight is pretty much like the thickness and viscosity is of course how fast it flows. heavy weight is usually has better lubrication properties but thickens up in cold weather; which is why 5w is preferred as motor oil. for transmission, from what ive seen, are usually around 75w.

actually incucivic is right; W stands for winter. like in multigrade oils like 10w-30; 10w is the viscosity rating for low temp(like for under 30 degrees F) and the 30 is the high temp viscosity rating.

75w is way too thick for the transmission. I used just a reg. 10w30.

i was refering to other manufacturers. if you go to the store you can probally find "Manual Transmission Fluid" with like 90 weight and such, but that doesnt mean its the right fluid for you.

I use 85w90 in my gremlin tranny. The W does stand for weight however. The higher number is viscosity when cold, lower number is viscoity when hot.

I know. I had the redline fluid that was at 90w but never used it. I would only use it if my tranny is built for performance.
