T56 magnum oil choices and tob sleeve

[mikevec87]

Hey guys I just purchased a new t56 magnum and was told to run royal purple syncomax but I heard alota guys suggest Amsoil signature series synthetic atf .

Also my t56 was plagued with noisy throwout bearings would the lethal performance throw out bearing sleeve be worth putting on the magnum or should I be less likely to have the noise because The magnum is still brand new.

Thanks

just a thought..

wouldn't something new have the updated shaft?

I got my Magnum trans used and it shifted great.

When I swapped it around I put Royal Purple in it (i think it was their ATF after Tremec said Mobil1 and Amsoil ATF were approved, not the synchromesh) and it shifted like absolute garbage. Drained it, filled with Amsoil and it was 90% better. Drained and refilled again when replacing the tailshift seal and its back to shifting great again.

Dex 3 only no syncomax or synthetic. I used Valvoline dex 3 atf. Used In 2 cars now. 1 F-body magnum with over 800+hp and 1 in my cobra. No problems at all.

I saved the ams oil for the motor and rear end.

I called Tremec when I changed my fluid and they said Amsoil atf would be fine. My car shifts better with the Amsoil.

I have ran RP and Amsoil ATF, AMSOIL is by far the best for shifting.. Noticeable difference!

I'm in the process of installing a Magnum as well. I plan to use regular Dex 3 for a 500 mile break-in and then Amsoil after that. Just be sure to use their "Synthetic Multi-Vehicle ATF" and not the newer "Fuel Efficient ATF".

Really a noticeable difference in shifts with the Ams?. Huh might have to look into that. Running the sig 3000 diesel and filter in my car now. So what's another 100$ lol

my trans shifted poorly, wanting to crunch/grind with the RP, no more with the amsoil. I attribute this more to the junk RP than anything

 

[mikevec87]

Sounds like the Amsoil synthetic multi vehicle ATF takes the win !

The Magnum suffers from the same hardware that plagued the T-56 like nylon thrust pads on the forks, plastic bushings, aluminum 5th and 6th forks and standard syncros all which can be upgraded. All that stuff is intended to improve the shifting action even further. It's a $600 upgrade when ordering the Magnum.

It's interesting peoples experience in improved shifting action just by changing the gear oil brands.

I've used RP, Amsoil, and did the so called anti-venom mod, in the last 2 years, my T56 still grinds especially when cold. No oil swap fix here Going back to factory recommended DEX III.

The T45 on my wifes GT hasn't been changed in 3 years and shifts like butter.

I switched to Mobil 1 on my T56 Magnum XL, and no difference. Mine grinds a little when cold. I drive it real easy for first few miles. Once it warms up, its perfect. I'm almost wondering if it might be the twin-disc clutch causing the cold grind?????

I don't know some people on here swear by the twin disc.
I just know for a fact that none of the miracle oils fixed the notchy-ness of my tranny.
