Automatic tranny fluid on manual tranny?

[andakanda]

Hi dudes

having some minor trouble with my tranny, some grinding when put into second gear, as if the synhronization is off or anything. Never been driven hard by me but dont know about previous owner

My mechanic buddy told me that maybe putting automatic tranny fluid into my manual tranny would help because the autoamtic tranny is abit thicker and will help "brake or slow down" the synchronization abit when changing gears ? Can anyone confirm this?

also i ordered a short shifter today , as told by the tech upgrade path here at dsmtuners

NO NO NO NO!!!!! you will mess that thing up to hi hell and back. sounds like you need a syncro. auto trans fluid is way thinner then gear oil my friend. your buddy is a moron.

Auto trans fluid is hydrolic fluid

Manual trans is Gear oil

I would NOT recommend putting automatic transmission fluid in your manual transmission. Have you checked to make sure that the fluid level is okay? If not, I would do that first. If it IS full I would first try to change out the fluid to see if that helps any. Good luck!

The first thing I would do is start looking for a new mechanic buddy.

Then I would check the fluid level as Matt suggested. If it's full, you may want to look into switching to a good performance gear oil like Redline MT90.

i know this is a very stupid question i got a 91 tsi 5speed where can i check/add the fluid

where can i check/add the fluid

On the front of the tranny casing (across from the radiator fan), is a bolt about mid height and in the middle of the gear area.

You pull the bolt out and poke a finger in the hole and it should come out wet. If not, you put GL-4, 75/95w gear oil in the hole until it starts to pour out of the hole. then put the bolt back on.

..and it's best to do this on level ground so you can get more accurate readings...


..and REDLINE MT-90 is great stuff!
