gearbox oil

[C50]

2 litres of sae 80 in my 2.5S driver's manual. Remember to use GL4. GL5 is not backwards compatible and will eat through the synchros [] very difficult to find fully synthetic sae 80 too. I'm weary to run multi grade 75w90 incase it causes resistance in shifting when cold

Two litres wont fill it: Id expect it to take a shade over 2.5l. This mistake was introduced in series two handbooks (from 2.6l) and it wasnt ever corrected.

Me being one of them! Probably one of the most significant changes made to the car. The change quality & lack of noise was amazing.

Swepco gets a lot of recommendations, but so does just changing the oil. I'd say the same as with the engine; any decent oil and change it regularly. And, check you can remove the filler before the drain.

Hi. I used this http://www.design911.co.uk/fu/pt376_1019_-cma81-cmo123/Porsche/944-1982-91/Gearbox-Oil/ Did a great job

 

[dave364634]

so either of the oils in my first post will do the job, and i must avoid gl5?

Yup & I'd go with a semi or full synth if you can
