roughground Posted May 30, 2019 Report Share Posted May 30, 2019 Can anyone give guidance on the type of oil for the TR7 5 speed box. I've read that the auto transmission fluid is not a good idea for longevity. The Haynes manual says EP75 but that seems difficult to find. Is EP80 OK or even the ep 75/90?

Slantfour Posted August 7, 2019 Report Share Posted August 7, 2019 I was recommended to use synthetic 75/80. ATF may have helped the change quality, but did nothing for durability. In those days your car had 12 months/12,000 mile warranty so not BL's problem! Quote Link to post Share on other sites
