So i have 67k right now and i haven't flushed or changed any flush but the oil and filter. what would be better replace the trans fluid ir flush it. Also how is the flush done?

 

OK that makes sense. Folks should change it regularly even if you don't flush.
The fluid gets revitalized with changes.
IF everything is operating normally and not overheating the ATF should not be stressed.
Actually, probably more danger in flushing later and never having done regular 'changes'.

 

I was having problems with my transmission at 34,000.
the dealership asked me if i'd had the fluid changed at 30k miles.
i said yes and provided them with the reciept from the shop that did it.
as a result, they replaced my tranny for free.
i asked them if i hadn't had my fluid changed if they would have covered the tranny.
they said no.

pay $150 now or risk $6000 later.
your call.
I'm damn happy I followed the book.

 

You need to flush your cooling system and refill, drain and refill your transmission and differential.

 

what about power steering fluid and fuel injection? are they needed for 30K mile service?

 

I always thought that replacing the fluids, along with the trans filter was the way to go.

However, most dealerships, w/Auto Transmissions, recommend a flush.
It is simply a machine the evacuates all the old trans fluid, and replenishes with new fluid at the same time....it more or less pushes out all the old fluid through the trans/filter/valve body/trans cooler, the entire system, as new fluid replaces it. The machine is set to the appropriate amount of fluid, and once it has been pumped in, its completely flushed out the transmission.

I had it done on my last two cars, and have had no problems with the trans..... It appears to be as good or some say better than a gravity drain.

On a manual, I think the replacing is the only way to go.

 

pwr steering is fine. fuel injection, you can just throw a bottle of bg44k and you'll be fine.

 

When I do some fluid flushes (mainly brake fluid and coolant) I also siphon out the PS reservoir and refill with fresh fluid. That's not even required, but having it flushed does more for the dealer's profit than the car IMO.

 

Thanks and now i have to get my car on to the lift at work and do it. Has anyone but different diff fluid in than oem? trans is gonna have to wait tell next pay check. how much does that ran again?
