I'm slowly knocking off the maint. items off my check list. Next up is the tranny fluid needs to be changed.
I have a 92 SC400, with 126k miles. I don't know the history on the vehicle.
It clunks when shifting into Drive or reverse. But otherwise shifts smoothly through the gears while driving. It's not severly bad, but it is noticable.
I was thinking of taking it to Aamco to have them do a power flush and refill it with new fluid.
I've read that it's not a good idea on high milage engines that have not had this done before. Does anyone know if there will be any problems with getting this done? Also will this fix my clunking problem when shifting into gears.
thanks in advance.

It's not good to shove fluid through the system. It's always good to flush it, old fluid & deposites are nasty. Not flushing transmission fluid is what keeps the old mechanics that came up with that BS in biz in the first place.
AFA power flushing, it depends on which machine it is. I think the best way is just pulling the cooler lines off & letting it do it itself. It's basically a high speed drain & fill that get's almost every drop of fluid out instead of just a small percentage like a drain & fill of the pans do.
Let's face it. Most A/T transmission pumps make between 150-280psi anyway. They can shove the crap out of the valve body by themselves without help.

Two more quick question.
1) What's the total amount of ATF fluid I need to replace if I'm going to drop the pan and drain from the radiator as well?
2) What type of ATF do I need for a 92 SC400?
thanks
also for anyone looking to do this in the future, I found some great instructions on this site:
