What fluid is everyone using in their magnum trans?Anyone using royal purple fluid?search function is down.
not sure what was in mine when I got it but it shifted great.
I drained it when pulling it for a driveline swap and refilled with royal purple, did not like how it shifted.
I refilled with Amsoil ATF this time around but havent been able to drive it yet...I think Mobil 1 would be fine as well (the mobil 1 synthetic ATF IS approved by tremec for this trans now
Amsoil ATF
DO NOT use RP, that is what I have in there now and as soon as it gets hot its terrible. I am swapping out for Pennzoil syncromesh

Yeah I ran across some info back in the day saying RP (ATF not Synchromax) is a no go and bad for the laminate on the synchros or something to that effect. Buuuuut, Jimmysidecar says they use Synchromax in all theirs so who knows. I'm no expert but spent a lot of time reading others experiences with different fluids. I'll tell you I noticed a marked improvement in the Amsoil over the Coastal ATF I used for the break-in. From what I gathered from Tremec the ATF provides enough bearing lube while letting the modern synchro material to function properly. Synchromesh is a bit slippery for the friction material, at least that's the Internet consensus. :shrug:
Amsoil ATF
+1 mine loves the stuff. Spent a lot of time researching what fluid when I got mine. A lot of guys use synchromesh too but since the case says Dexron III and tremec says only synchromesh for the TKO 5-Speed I went Amsoil Signature ATF. I think I started a magnum fluid thread on here a couple months back.
Amsoil
Yep. I tried the Mobil 1 Synthetic and it was better than whatever Ford put in there stock. But I still had a hard time shifting into third from second.
Then I drained it and put in Amsoil ATF. It shifted much better, but still wasn't perfect.
Replacing the clutch quadrant, and getting an MGW shifter took care of the rest.
I stuck with the Ford clutch cable. And I did it so long ago I was able to get the Fiore adjuster and quadrant.
You sure youre talking about the Magnum T56? last time I talked to MGW they didnt have a shifter for the Magnum due to some odd gear spacing and he hadnt come up with anything he was happy with.
I did get to drive the car a bit with the Mobil 1 and the second gear issue I had with RP is gone, it all around shifts better now.
