TransSurgeon.

I recall you replying to a post not too long ago about flushing the tranny fluid
in an automatic. You mentioned something about the distributing dirt from the
converter. Would you mind being a bit more specific on the details? I did not
quite understand what you were getting at and the implications of doing this. If
I recall you indicated to just change the fluid. Could you post, the various
methods. The pros and cons. What is best and why.

E.g. Compare Power Flush. Replace fluid and filter. Replace fluid. and other
possible options. What about using detergents/additive before doing a fluid
change? What about additives after?

If the vehicle details matter. I've got a 94 Ranger XLT 4X4. 4.0 - V6 with the
A4LD automatic transmission. 3.27 conventional rear end. 66,000 Km or 41,000
miles.

As far as I know nothing has been done to the fluids to date. I've been told I
need to replace the modulator valve and it was suggested that I do a fluid flush
at the same time. Should I be doing anything to the other drive train fluids. If
so when?Anything I should be keeping my eye out for?

Thanks,

fluid flushing is snake oil

it will knock loose the dirt in the converter, which then plugs the cooler,
or if it makes it thru there, becomes lube oil

the A$, especially, does not like 'fluid flushes', I've had two in here that
were flushed and would not back up afterwards..........the one-way clutch in
the OD assembly would not engage after the flush

of course, Goofy Lube claimed it wasn't hteir fault

well, whose fault is it when the vehicle is driven onto the lift, the flush
is done, and it won't move afterwards ?

regular fluid and filter changes cost less and are more effective because
you are not allowing dirt to get into the lube circuit

Thanks,

What do you recommend for the timing of "regular" fluid /filter changes? Should
I also be doing anything with the other fluids?
