The maker? of it, (kind?)
id' say its made by a top transmission maker in japan.
and fully spec'd out by Isuzu.
why do you ask?

  • need parts.?
  • curious.?
  • what?
  • does it fit other cars?, why not ask a transmission exhange shop or rebuilder. that. they can answer, that.
most transmissions of this type use a standard box but with OEM
tail shaft houses, designed by Isuzu to fit transfer case .
see here for the kits and gives you and idea of what cars it fits

for a diesel I have no idea, google exchanges for that.
google tranny rebuild kits.
or google swaps. for same.

i do manuals. and best is to find a donor car.
then pull the tranny and have 2 tranny
then get the kit and make one good transmission.

you never stated the problem with it?
one bad syncho? or whines or pops out of gear. or ???????????????????????????????????????
dragging clutch>?
will not shift?
stuck in 1 gear.
stuck in neutral , ?

SOURCE: Transmission Fluid - 1987 Mercedes-Benz Diesel Turbo

It took Mercon Dextron III.

Of course, MD IV, V or Mutli-Vehicle would be better (the new multi-vehicle formula is what is being widely recommended by all nowadays).

SOURCE: What kind of fluid do

If the vehicle has an Automatic Transmission: Dextron II

If the vehicle has a Manual Trans, its complicated.
Depending on Trans model:
The 77mm 5-speed and 89mm 4-speed overdrive use Dextron II ATF.
The 117mm 4-speed uses API GL5 SAE 80W90 gear lubricant.
GM recommends Synchromesh Trans Fluid (1052931) in both the 85mm 4-speed and 5-speed.
Hope this helps!

The transfer case is stuck in the low range. If manual shift try shifting from low to high several times to see if free up. If electronic, check all fuses and make sure you hear transfer case change range. Do this by shifting with key on engine off. If no change refer to qualified transmission mechanic.

Do you have to drop the transfer case when you change transmissions on a 94 GMC long bed extended cab pickup 4x4 with teh 6.5 turbo desil

no you should not have to drop it. there should be a slip yoke with the shaft leading from the transmission to the transfer case. when you remove that and support the transfer case there will be plenty of room to move the transmssion back away from the engine to remove it
