well i been reading a few threads about tranny fluid and i wanted to use royal purple this time but I'm not sure if people were use 10w30 motor oil or 75w-90 gear oil. can anyone help me?

 

i just used the oem stuff its $9 a quart but at least you know your getting what it needs you should only need 2.5 quarts

 

anyone

 

I put in Redline MTF 75w90 in my SiR tranny...shifts like butter and it's probably the best transmission I've ever used...ever. 2 Bottles, I need to buy another one so I can put a little more in there.

75w90!?! You are recommending oil that is thicker than Honda says to use?

Back before Honda made their own MTF, they used regular 10w30 in their 5-speeds. Using normal non synthetic, non high mileage type conventional 10w30 motor will not hurt your 5-speed tranny.

I have used Honda MTF and GM Syncromesh and felt no difference in gear engagment smoothness. /.02

Most take 1.9 qts.

 

so can i use Pennzoil sync. and MTF?? or can i use sync and royal purple

 

I can't reccomend mixing MTFs. I don't know if it's ok. I didn't mean to imply that in my first post.

X2, 75w90 is thick, really thick, even snow plows usually only run about 50 weight motor oil in their trannys. For some reason toyota specs 75w90 in their light trucks though.

10w30 or honda MTF is my recomendation.

 

so royal purple 10-30

Should be fine, although personally i've heard great stuff about honda's own MTF, haven't actually tried it yet so I can't comment on it.
