A mechanic told me power flushing an old automatic transmission can ruin it

[Q45tech]

A BG mechanical exchange is no more stressful than a series of 4-5 pan drains and refills WITHOUT the BG QUICK CLEAN SOLVENT.

We have customers who request no solvent be added and we are happy to follow their wishes and delete the 10 minutes [$8.50] of chrunning and $8 the solvent costs.

I beg to differ with that theory, as with the BG machine, you are forcing the transmission pump to force a large column of 14-16 quarts of freah ATF out of the machine and into the transmission- certainly ALOT more work than the transmission pump normally does while circulating atf through the small diameter cooling lines. The drain/fill operation creates ZERO extra work for the transmission pump.
