Quick question guys...I have 3 litres of tranny fluid for my T5. Is this enough fluid? One more thing what is a good way of filling it? Can I just fill it through the shifter hole (the shifter isnt even on the tranny right now)?
THanks

T5 take 5.6 pints of fluid. I've never filled through shifter always the fill hole on passenger side of tranny.

The 3 liters should be pleny - use high quality Dexon or Mercon type ATF fluid. You can fill through the shifter OK. I would wait until the trans is installed to fill it. It you don't wait, you will spill fluid when you tilt the trans to install it. Then you have to lay in it while getting the trans installed.

I usually just unscrew the top pipe filler plug and stick a 6 foot piece of garden hose in it. I put a catch pan under the trans to catch the overflow. Then I put a funnel on the other end and sit down on the doorsill and pour away. When the trans is full, it will start dripping fluid out into the catch pan. Put the top filler plug back in, tighten it down good and you are done. The trans will have the right amount of fluid, no guessing or having the wrong amount.

Not for a stock Ford Branded T-5. The Ford version of the T-5 uses ATF (Dex/Mec III)

If you have a different transmission, check with the builder or any reference material to verify transmission fluid recommendations.

That will supposedly be a very bad thing to put heavyweight gear oil in there! I've never tried it, but I imagine it would be bad. ATF FTW!!!

Yeah 75w90 in a T-5 is a bit thick. I always used Redline D4 ATF. Oddly enough though, my DD takes 75W90 synthetic gear oil.

I think '85 was the first year of the WC T5, which takes ATF.

Very early T5's did use gear oil.
