Should I use oil or Honda Transmission fluid. Why is because it's Grinding on third gear. I ask some people an they say to use Honda Transmission fluid because the Transmission has LSD on it.

So which one should I use Honda fluid or oil?

 

Honda manual transmission fluid is the best, hands down

 

Use the fluid the LSD maker recommends.

Old Honda MTF (1st gen) was great. The pisswater they sell now sucks for older transmissions. For 87 Teg 10w30 is perfect.

 

Will its a 92 cable LSD transmissions. So I will have to go Honda fluid

 

10w30 will be fine.

 

What LSD is in it?

Fluid will not fix a grind, only cover it up making you think it is fixed but hurting your wallet more in the long run. Do not run Honda MTF. 10w-30 is much better to use.

 

A defective gear shift is caused by driver error, defective linkage, or defective parts within the transmission. No fluid will cure this, only mask it. Pull it out, and inspect it.

 

I agree. Is it just 3rd gear? If so, your probably gonna need to rebuild or replace... changing the oil isnt going to fix it.. just prolong the inevitable... (failure) look into a used trans. And swap it.

 

It only Grind on third gear when you race that all it drive normal

 

That statement is 100% wrong.
