Did anyone mention Dexron?

I await a shot from an RPG emanating from the North East!

Never even thought to mention that it does have to be automatic transmission fluid. NOT gearbox oil. You did realise that didn't you 70rtse?
Don't scare me.

Dexron is OK.

Dave, sisn't 9 litres a bit much? I put in 6-7 and still had to let some out of my 727. Stock pan.

yeah but you need 2 liters to make that decent sized puddle that you put your head in every time you change the gearbox oil

well i do

Torque converter takes a fair bit too. And you drain that when you change the oil.
I will double check on the total amount later (It was off the top of my head) unless someone does it for me first..

OK. Home now.

I was right in that a 727 behind a 440 has a total capacity of (according to the 1970 Challenger owners manual) 9 litres.

However. Depending on what engine you had it varies. A hemi trans only takes 8 litres. A 383 bbl is down as 7.8 litres but the 383 2bbl is the same as the 440 at 9 litres.

Go figure.

Here it is from the "Factory Workshop Manual".

One UK Pint = 0.568261 litres.

Hmm? i thought i'd overfilled mine as I had fluid leaking from the bellhousing even with about 7 litres. Dipstick certainly read high at the time, drained of a litre or so and the leak pretty much stopped. All new tranny and seals so i figured i overfilled it.

Remember that is bone dry capacities and the converter probably takes something like 2 liters. I think with my deep sump I ended up using all of the 10 liters of Titan ATF 3000 (Dexron II) I bought.

The decision to use this fluid was based on both its low price, availability from my local motor factors, and the fact it comes in 5 litre bottles.

Fuchs Titan is what I use,get it from a local digger place, same price. Better than £9 a litre from Halfrauds.
