I have a 2011 ve ssv s2 with the L77 and 6l80 6-speed auto.
Have been noticing some flare between gear changes (mainly 2nd-3rd for a while, not drastic but noticeable.
Recently noticed trans fluid in my radiator (most likely unrelated) turned out the trans cooler on the radiator had let go which filled the cooling system with trans milkshake. Completely flushed the system several times over, replaced radiator and all hoses, flushed the system another seven times until all clear.
Then topped up the trans (correctly) untill it over-flowed expecting to see a milk shake in there but surprisingly enough the fluid in the trans was pretty clear.
Naturally I thought the initial gear flaring was caused by the gradual loss of trans fluid so was hoping that once I filled trans back up (lost about 2litres) it would be operating well again.
Unfortunately Gears still flare and now it’s having a hesitant start in drive. It starts moving then stops and immediately jumps back into gear.
Have spoken to several mechanics and only advice I get is rebuild or replace, have also spoken to several auto specialists and a couple said this particular transmission (1CVA) was prone to a crack in the drum internally and can often be repaired reasonably cheaply. Which leads me to my 2 questions;
*has anyone out there had a similar issue with there 6-speed 6L80 (1CVA) and did an inexpensive repair solve it?
*if I am up for another gearbox can I pair a different 6L80 6-speed (with a different sticker code on the side) to my L77 6.0 without too much issue? I’ve spoke with Holden and they won’t touch anything that isn’t an exact match to the car/engine but have been told it’s more then possible to do so by a few people, a couple people on here said it’s easy enough as well.
Really appreciate picking anyone’s brains on this subject before I go and shell out 6k for a rebuild or replace.
Cheers
