Has anyone used Amsoil in the A-833 trans. I am a dealer and I am a firm believer in the product.I just had a friend go through my A-833 in my sons 87 D-100 and replaced bearings and any thing else that could cause a potential problem. Now we are ready to start installing engine and trans. Also what weight would I need using the Amsoil?

ATF has been specified in the A833, but I think it's a little thin in most climates. You can use SAE 90 with no problems just so long as it's GL-4. GL-5 is too slippery and the synchronizers have a tough time and the box is hard to shift. As a dealer I'd think you'd have a good idea on a couple different products which would work. I use Red Line MT-90 myself and it works very well.

The reason I inquired about the Amsoil is I have run into some trans (Honda) that do not do well with the synthetic and it is strongly recommended not to use it. The GL-5 is for newer trans applications? Thanks for getting back with me,

Me, I would recommend using the type of fluid, lube, or oil recommended for the particular unit in question -- no matter what brand you choose.

Augie Dog, The Amsoil to use in your app is the MTG (GL-4). A 75w-90

Thank you Ryan. My head was hurting and I might have said something less kind or helpful.

The factor fill on the later a833 was ATF. Thats what my 83 is required to use. I ran the synchro mesh from Ams Oil in it and it shifted like a dream. Now I got the 75w90 from ams oil and it was fine in hot climates but the colder below 80 the harder it gets to shift and the blocking rings to work right. It is a lot quiter I have to admit and on a road trip of 1450 miles it was just a little stiffer shifting- more like the NP 435.

Yesterday I picked up the 83 D-150 a-833 from Brewers. The truck - tranny is a one owner, 110K miles. The folks at Brewers commented it was one of the better trannys they ever seen,, not abused,they replaced the input out bearings - seals- syncros...

I had it re done as part of the general rebuild on the 83 D,, had a bit of bearing whine to it, I think from sitting, as that got better with time, but never went away,,and I never thought the shifting with it was anything that could be called smooth or quick...

anyway it had always ran ATF,,the folks at Brewers recommended 80w90,. Is the Red Line MT-90 the 90 weight oil that it sounds like? I may start with ATF and then give the Red Line MT-90 a try for comparison.

Yes, Red Line MT-90 is an 80W-90 GL4 gear oil.

Be careful of the gear oils-some are corrosive to the synchros,yellow metal.And a A833 is on the noisy side.Just in a track there isn't enough sound deading material in the cab to isolate it.

Actually the MT90 is a 75w90. Redline currently doesn't make an 80w90.

I use a truck 833OD in my car and filled it with Lucas 80w-90 conventional oil mixed with a half quart ATF. I thinned it only because at the time I was thinking 80w-90 was a little thick. And, this was all during the peak of summer so my thinking my have been off. Regardless, it shifted fine but with the cold weather lately, I'm noticing it shifts a little harder into all gears. It's barely enough to notice... I rebuilt mine myself and worked around some mainshaft wear and I've seen the "noises" get quieter after break-in. Still not quiet like I'd like but liveable.. Ronnie

I'm wondering what I should do for a winter fill?
