I changed the brake/clutch fluid today for Motul RBF600. As reported the old stiff was like cola.....what a difference in brake feel!
I would like to change the transmission fluid. Does anyone have a step by step (video/ pictures) of how to do that?
Just changed mine today :
I went with the Redline MT 90 ( as listed elsewhere in this thread)
2011 Evora, 20k miles.
Drain plug - 24 mm on lower part of 'crown' of transmission
Fill plug also 24mm 1/2 way up on driver's side of same unit ( if drain is at 6:00 - fill is at 9:00 when looking from back towards front. Fill plug looks like drain plug and has a notation on it " read manual before filling")
I drove car to warm up tranny and engine oil - changed this too. Raise Lotus , remove rear under tray. Remove fill plug ( to vent ) some oil escaped with pressure release - a tad messy.
Place catch basin, remove drain plug and drain. Clean drain plug and replace.
I purchased a cheap gear oil pump from Autozone , with a simple hose to introduce the lube into fill opening. The Evora manual says 2.3 liter , I added 2.5 quarts - until oil began to escape the fill opening. It did take 2.5 qts to begin dripping out - means it is level full.
Immediately shifts are 25% cleaner and there is a pleasing and positive click - clack that was lacking before.
By the way the old oil appeared to have good viscosity and not too dirty ( for gear oil) so you could say it may not have been needed - but tranny shifts much more nicely and I feel better about the service.
I considered taking pics but this can be messy and no place for an IPhone.
Redline must be the slipperiest, slimiest stuff I have ever played with.
This is pretty simple service. Good luck!
