tr6060 TR6060 Notchiness After Penrite Pro Gear 70W75

[LukB412]

Hi all,

 

I recently dropped about 3.5l of what I assume to be ATF (bright red colour) out of my TR6060 in my NA 2012 FG MKII Falcon, due to some 1st-2nd stubbornness when cold and general notchiness. I replaced it with Penrite's Pro Gear 70w75, as recommend by some forum users, but I believe this to have been a mistake.

 

After a few hundred KMs of improved shift feel, it has since degraded significantly. 1st-2nd is almost impossible without double clutching, and every other gear is noticeably more stubborn than before. It does improve when warm, but 1st to 2nd remains extraordinarily difficult.

 

I believe I did everything right. Drained when warm and filled it up to the reverse lock-out hole on the driver's side rather than the fill port. My questions are this: Has anybody else experienced anything similar? Am I better off dropping the fluid again and running penrite ATF FS or even Redline D4? Is it possible that I overfilled it? I've also noticed several members on Late model camira forums citing 3.5l as the fill capacity on their TR6060s. Does it differ between theirs and the falcon?

 

Would appreciate any help!

Fill capacity can differ... but yeah, drop the oil ASAP and see if you can re-fill it with something that's meant to be in it.

Thanks, Keith. Any fluids in particular you recommend?

DEXRON-III (DEX3 is the common name), it's actually marked as "ATF" (Automatic Transmission Fluid) but it's fine for a TR6060/T56

Thanks, Keith. Greatly appreciated!
