T-45 fluid Qs

stangen97 · Jun 8, 2005

I seen where the 3650 guys have changed their fluid and had fixed probloms such as noise smother shifts and 1-2 shift grind. Well I have a 1-2 shift grind and was wondering what the best fluid is out their I am running redline in it now. What is the worst fluid youve ran? whats the best? thanks

Tremec recommends Mercon III. That's what I used last time but I just picked up 4 fresh qts yesterday. I'm hoping it helps my 1-2 grind. I've heard the syns don't help much so I just went with what is recommended. Hopefully someone has had some luck with something else.

i use Castrol SYNTEC Full Synthetic Dexron III / Mercon .

SVTOA (svt club) claims a short throw shifter helps with the 1-2 grind. I'd say it did a little.

It helps to prevent it more than it does to cure it.

Thanks for the replys.I have the tri ax shifter in it,its adjusted right and i dident drive it much with out it on the car. I guess ill replace it soon with the recomended mercon3.1-2 grind is so annoying some times it does it some times it dont and it gets embarasing.

stangen97 · Jun 8, 2005

See some days it does it some it dont.Today i went out and no grind the most i got it up to is 4800 in first so ummmmmm im at a loss i guess if i get to annoyed with it ill go to mercon3 this weekend.
Does enyone have a prothane or solid or energy suspention tranny mount? I was thinking of getting one to get rid of the slopp but need some input.
THANKS

i dont grind on 1-2, but am I the only one that grinds going into 5th and reverse?

stangen97 · Jun 9, 2005

5th is ok here and reverse is a pita sumtimes but never grinds. What fluid you run?

COramprat · Jun 9, 2005

Reverse will grind or be hard to get it in gear because it has no synchro. You can put it in 1st, roll forward a little then put it into reverse. Another thing you can do is hold the clutch in for about 10 seconds then put it in reverse.

try "GM" syncromesh fluid
steeda sells it and any "GM" dealer can get it
It will improve shifting even that 1-2 grind.

stangen97 · Jun 9, 2005

Yeah the gm synchromesh hasent had eny bad remarks so i might try that.

mr. jones1 · Jun 9, 2005

my 98 has it for one year. it improved all shifts and the one two grind went away-(it did take a month or two)
this is what steeda recommends for the ford trans.

cobranos · Jun 9, 2005

Use AMSOIL synthetic......Much better than syncromesh and it ain't made by GM...........

stangen97 · Jun 10, 2005

Hummmmm well went out tonight and embarassment. well amsoil is good chit i run it in the motor and it does me good.Enyone try both gm and amsoil.

Joel's98GT · Jun 10, 2005

i've used a few syntyhetic fluids in my t-45 and by far the best is Royal purple Max ATF, it shifts smooth and I am actually swithching back to RP FROM syncromesh (which i have now) I had syncromesh in an earlier tranny too and I prefer the RP.

mr. jones1 · Jun 10, 2005

just wondering did any of the synthetic users have the 1-2 grind?
If yes, did it stop after using syn. fluid?
many praise amsoil and RP I have not tried them yet (in the trans).
