what kind tranny oil should we use? gear oil???
does Synthetic 75W90 Gear Oil works fine on s2k?

 

Nope DO NOT use 75W90 gear oil in the transmission. You should use nothing else than Honda MTF.

Some people have success with GM Synchromech but thats because some have experienced abnormal grinding or hard to shift conditions. Use Honda MTF if your transmission is working with no issues.

I bought this car in used, when I bought the car, felt the MTF not enough, so I changed other unknow brand gear oil, but works sux.....
And I saw the Mobil 1 Synthetic 75W90 gear oil today, and I am thinking to change it, but I am not sure how good or bad is it, just ask for more opinion and options.

thx guys

Gear oil is for the diff. not the transmission. If your going to swap the tranny flui,d then go with GM Syncromesh FM. I swapped to it today and love it to death. My tranny didn't grind before, but I had some notchiness and now it is completely gone.

 

I replaced mine with red line mt-90 and it works better than the honda mtf, at least in my car. it may br differnt in yours. I will be trying the GM oil at the next service. drive safe

 

where can I get GM Syncromesh FM?

 

notice the GM in the GM Syncromesh FM name? any GM/Chevy/Pontiact dealer parts dept.
