what transmission fluid/gear oil is best?

[ryanM]

im doing my 90k tuneup soon and im going to change my transmission fluid, and i dont know what to buy. i hear redline is the best, but i dont know what viscosity to get, can anyone help me?

and also for my tune up im doing: oil/oil filter change, coolant flush, new fuel filter, new air filter (my k&n has holes in it so i bought a AEM dry flow), and cap and rotor. my plugs and wires are still very new, so is there anything i'm missing that i should do/check?

honda mtf. its in my $2k built tranny. if the tranny is grinding, run gm syncromesh with friction modfier.

Had Redline MTF in mines for about roughly 60K miles now and not a problem yet. Think it was bout 2 1/2 quarts.

nothing wrong with redline, but its more $$ and honestly doesnt do anything honda mtf doesnt.

LoL. Yes I agree. Change it at about 75K and didn't notice any different.

But, on my bros GSR it did improve shifting quite a bit, it was easier to flow through the gears. His was change at 90K however, so I cannot assure whether it was just that the tranny fluid need changing or if Redline improve it.

what viscosity, should i get 75w80w?
edit, i meant 75w80w

what viscosity, should i get 25w80w?

get what the dealer reccomends for your tranny, they are different. if you cant run honda mtf, it says to run 5 or 10w30 motor oil, so id say 80 is too thick. using too thick of a gear oil can cause the bearings to not get adequate lubrication and die.

 

[ryanM]

just to help out, this is where im looking at fluid http://www.prostreetonline.com/buy/redline/ i dont know which one to get theirs 75w/80w, and MT-90 anyone know which one i should get? and i dont know what the factory fluid is either.

dont get any if you dont know the right one. seriously, just wait till tomarrow, call the dealer, and find out. my local dealer carries the honda specific redline products. or just buy the mtf and not worry about anything. as far as i know honda doesnt list the weight of its mtf.

alright, i'll just buy the Honda MTF from IL4, will 4qts be enough?

umm, i'm not sure, its stock on my d16y8. sticker on it says k4f but i dont know if thats the right one

go to autozone and buy pennzoil synchromesh. there is only 1 type of it. buy it. i run it in mine and its just fine. the shifting is much smoother IMO. i got mine for $5 a quart and used 2 quarts in my s20 (d-series trans). i know many people with hondas that sware by synchromesh, including one who rebuilds them. but do what you want
