ATF+4 and Dexron III seem to be widely recommended for use in the Torqueflite 727. I have chosen Comma MVATF+ as it is readily available from Halfords amongst others.

Do you have a limited slip diff in your back axle?

Hello Martin.

I contacted Morris Oils to check what they recommend for your rear axle. They suggest their XEP 80W90 is what you need.
