just passing along what is working for me...

when I re newed the 83 D150 back in 2010 I had the A833 tranny gone through by Brewers

ATF was what I drained out of the tranny when I pulled it and ATF as specified by the FSM is what went back in.

January of 2017 after 21642 miles I changed out the ATF for Redline MT-90 GL-4 fluid
the transmission shifted OK with the ATF but I was looking for something better and
the Redline MT-90 has good reports in several internet forums.

This OD A833 just never shifted well with the MT-90. If I hurried the shift at all, I would get
gear clash, especially from 2nd to 3rd.

If I shifted slow, like move from first, wait a half second, and pull into second,
shift from second, wait,,then push the shifter into third,,,
it would shift ok,, felt like I was waiting on the syncro's to align the next gear.

I tried improving the adjustment on the shift linkage,, made no difference.

I drained out the MT-90 with 9000 miles on it ( yes I have 29630 miles on the D150, my how the miles fly by) and refilled the A833 case with
Sta-Lube 85W90 GL-4 Gear Oil.
This is what I was after, shifts real nice, the next gear just clicks in place.
No waiting.

I found the Sta-Lube at NAPA, was $35.00 a gallon, but well worth it.

Good to know, and thanks for sharing. I'll be installing the same tranny, also newly rebuilt, in the near future.

Odd. I had the opposite experience. Cheap GL-5 was good shifting, but RedLine MT-90 gave excellent shifting. This was with a standard A833 however. And it had never been overhauled.
