Hi all I am changing all fluids in my 1989 2.1 auto caravell, I have done the engine oil, auto trans fluid am not able to locate drain and fill plug for gearbox oil, help please cheers Mawsy

no drain plug on T25 auto box

remove sump to drain and replace filter then fill through dipstick tube.

both very easy Gasket and filter available from Brickwerks (you can clean the filter with spray brake cleaner but rubber sump gasket needs replacing every time.

also make sure sump is not distorted abound its fixing bolts as it will weep if not completely flat.

Thanks for that, thought I had lost the plot, will order deals and complete weather permitting cheers Mawsy

What is the amount of gearbox oil required, it states 3.5 litres for manual box cheers Mawsy

its all in the wiki

careful you don't over fill the box ....

The gearbox is in 2 halves ,The Auto trans part that takes automatic transmission fluid

The differential that takes gear oil

You have to drain the 2 halves and fill the 2 halves separately

This might make it more understandable.

The auto gearbox takes take 3 litres ATF and final drive 1.25 litres. SAE 90 GL5.

Gearbox. Remove pan from gearbox to empty. Clean out filter/strainer or replace. Fit a new rubber seal on refit. A bugger to do BTW as the rubber seal refuses to stay in place. Do not over tighten bolts on pan. 20nm. Refill through dipstick. Do not overfill.
Final drive. The bit with drive shafts. Empty through drain plug. Refill through oil filler plug/ level plug

Just seen Cobra's photo stating 2.5 instead of my Haynes manual of 3 litres.
Go through filling procedure and be certain not to overfill
