New Amsoil MTF

Anyone have any thoughts on the new MTF that Amsoil has come out with?

TOO THICK!

Use redline MTL. Not Redline MTF. ONce again. Redline MTL.

MTL good, MTF bad.

I recently did a fluid change and switched from Mobile 1 synth (or it might have been Castrol 4x4 synth) to MTL and I removed a bunch of gunk from the filter. Alot, actually. Nothing hard, more like thin sheets of flakey black paper like crap. I refilled with MTL. Now I snick going into 2nd and if the truck is cold, it grinds into second. When warm, it is not too bad. I know part of this is the cleaner fluid, but I have to say for the price, I would hesitate getting the MTL. Now, if I refilled with some other fluid, the snicking may have been 10 times worse, so I am not saying it WAS the MTL, but I won't know till I change the fluid again--and having spent $60 on the fluid, I am not going to do it just to check. FWIW.

Hmm... You have a 94 D90 5spd R380 and you removed thin sheets of flakey black crap from your transmission filter ? Where is that 'transmission filter' located ?

Please forgive my ignorance.

P.S. Great post... I haven't been keeping up with the oil shtuff lately! I'm on it the next time I change the fluid out, maybe sooner. It shifts ok... so far, a little sticking in 2nd but most do.

MTL is thicker so the synchros do not go as quick when cold. This is good as they do not wear as much as the MTL cushions them. If you are snicking at all you are shifting too fast.

If you want fast shifts run ATF, but the synchros will die quick.

I just switched from Mobil 1 Synthetic ATF (it was available) to Redline MTL. The ATF felt like shifting a box full of water - the MTL feels like its full of lube. That makes me happy.

Put the 5/30w Amsoil MTF in my '94's R380 and it seems fine - a definite improvement over whatever was in there before. I am not sure how this Amsoil product compares with the Redline MTL; the write-ups make it seem they are roughly equivalent in lubricating and cushioning the gears and synchros. Perhaps one of the lube gurus will enlighten us all. (?)

Redline MTL is the best thing you can do for your gearbox

Well, it turns out that the flakey bits were actually paint that they use on the inside of the gearbox--it is so that the oil drains off the surface easier (they still use this "technique"). The gearbox only snicks in cold weather and then just for the first 5 minutes or so, then no snicking at all. I say snicking, but when really cold, the second gear actually grinds a little. I have no snicking once warm. I suppose I could be convinced that MTL is doing its job...

If it grinds you are shifting too fast. Slow it down and no grind.

:-) Yeah, sure wish it was an R380. No one ever complains about those grinding. Oh, to dream.

My R380 used to grind second, but I just learned to drive it right.

I agree with Ron, the only time I've had any grinding or "snicking" is when I've shifted too fast. A lot of good feedback in this post. I guess at some point I'm going to have to try the Redline MTL, but for the past year I've had Amsoil ATF in the gearbox and I have no complaints. It shifts smoothly cold or hot (definitely a bit smoother when warm though). That's why I was curious about these two new products from them. How often do you guys change that gearbox oil, once a year?
