Eneos 75w-90

 

I'd do it every 50k. I second Eneos. I tried Motul, and it wasnt as smooth as the Eneos I put in after a new clutch.

 

I changed mine at 38k and I will do it again in another 38k at most. I used Royal Purple.

 

With full synthetic and normal driving you only need to change it about every 75k......

Ive used two different ones since I bought my 07tc back in late 2006.....Redline MT-90 and Royal Purple.......IMHO Royal Purple is excellent (I use their engine oil as well) but the Redline MT-90 can't be beat for synthetic tranny fluid.....a little pricey but definitely worth it for silky smooth shifting day in and day out

 

If you live in a cold weather state like me. I run a cocktail

2 quarts of Pennzoil Syncromesh and .7 quarts of Eneos 75w-90.

Works excellent in both winter and summer conditions. I find that 75w-90 is to think for us cold state people.

 

Get better mileage and more power to the wheels with Synlube gear oil, shifts with 1 finger!

thanks bros

 

My experience; at 100k I replaced the Gear oil with Royal Purple.
This winter I was having a hard time shifting gears in the morning. I ordered Amsoil. I opened the drain plug and nothing comes out. Not a drop of the Royal Purple oil. Where did it go? I have no oil stains under my car where I park. I added Amsoil at 146, 500 and my car is again shifting like new. I don't how long transmission is been dry.
