What should be done by now outside of new air filter, oil changes, etc.? A transmission fluid change? Valve job? I'm running custom tuning, 2.7 pulley, 60's, catless dp on a stock sssc exhaust. Car is an 05 LSJ.

Thanks-

 

85k and running strong?? nice dude

 

iirc gm says the trany is fill for life, however id change the fluid at that milage, wont hurt anything. with a 2.7 id also consider changing the s/c oil. it supposed to be service free but it is being spun much faster than originally intended.

 

you should be good outside of what has been mentioned. I have 88000miles on my 2.4 and I am changing my tranny oil, just routine maintinence should be fine

 

Trans fluid change.

Brake fluid flush(theres no spec for ths from GM but virtually every other manufacturer in the world has a service interval of 4 years or LESS, I say every two years.)

Getiing close to a coolant flush, spec is 5/150 miles but I like to do it by 100k.

Passenger compartment filter(every 30k miles or 2 years)

Supercharger oil(50k)

 

thanks guys, is there anything else I'm not thinking to do to take care of my car? Picked it up with about 77k miles on it.

 

OMG!!! thtas alot of miles!!!!! what year is it??

 

2005 Cobalt SS SC.
