Bought the car at 82k miles. Not sure if the previous owners changed the trans fluid. It's at 86k now. Should I change it? Like drain and flush? Or just partial drain and flush? Thanks.

 

Do not flush

drain and fill!

 

Do rear diff too while your at it

 

I'm assuming you're auto cuz you said flush..?

If so, yeah, don't flush. Just drain n fill.

If mt, obviously that's your only option. Just don't flush if you're auto.

 

Sorry yeah I meant drain and fill lol

 

Yeah, drain and fill.

 

I changed my atf on my g. Not sure if the previous owner had done it. I bought 5 quarts of valvoline max life atf. And also bought the transmission filter. I let all the oil drain out, then put everything back, and put 5 quarts of fluid. And here i am months later still running strong.
