Transmission Fluid change BJ42 1981 3.4B (1 Viewer)

Looking for clarification on drain plugs and re-fill

Diff case front and rear have sourced and drained

Main transmission can somebody comment on pictures, 2 drain plugs can be seen, refill plugs are the ones I would like confirming

RHS of gear box up high just above the main chassis rail is this the rear-fill ?

Large nut around 24mm on the back of transmission is the 2nd refill ?

Regarding fluids what’s best for main box and diffs 75w 80?

Refilling until it starts to dribble from from refill hole is enough ?

Thanks and any other tips appreciated

Yes. The clean on ein the second picture is your transfer case refill.

Transfercase drain should be on the bottom clearly visible.

Transmission-Drain on the bottom of the second picture. Transmission fill on the left upper side, app. in the area of the drain.

Regarding fluids what’s best for main box and diffs 75w 80?

I use a SEA90 GL4 on the transmission and transfer gearbox, BUT I live in Brazil But I'm pretty sure, the 75W80 will work as well.

On the Diffs I went for a 85W140 GL5. I like it thick in the diffs (and it's often hot down here)

Both are mineral grade, on the Landcruiser I change the oil more often then on a normal car.

Thanks for the advice, i have found the 2nd refill LHS

Oil dump cover how easy is this to remove, oil drained I’d thought about removing, bolts out but stuck fast, concerned about damaging the engine seal face trying to prise it, if it’s been stuck will sealant then a nightmare to get out…. Thoughts ?

Advice please, draining the LHS of the transmission

Re-fill nut 17mm
Drain 24mm

What is the big nut 2nd photo on the back ?

Plus when I loosened the re-fill nut transmission fluid poured out, if this an issue with the seal from the transmission to the transfer ?

Just to confirm

RHS is transmission ?
LHS Transfer case ?
