Tranny Fluid
 

I stopped by a local transmission shop today. This shop has been in business over 50 years, They rebuilt the tranny on my Ford 7.3 @ 202,000 mi. So far 140 ,000 trouble free mi.
I have a 95 MB with 284,000 mi on it and was going to have them service it. I have the filter, MB fluid (8qts.)& gasket. I bought the tranny kit from here with the MB fluid,filter ,etc He quoted me a price of $70 with drainning the torque converter.I thought that was reasonable.
However he recomened NOT draing the converter.
He said its been his experience that with todays tranny fluid especialy MB high detergency level he did not recomend flushes or draining the converter on high mileage vehicles because it creates problems. He advised me to do (2) 4qt change intervals. He said I'll drop the pan change the filter for $40 come back in 40,000 mi and we will do it again. What do you think

I'd look for someone to do it as the manual says to do it.

I believe I'll take the mans advice . With over 40yrs rebuilding various trannys & servicing he has alot of experience. Thanks for the replies

ZF has been in business for 96 years ;)

Seriously, would he drain the TC for run-of-the-mill Dexron III as specified in the manual? Doesn't 95+% fresh Dex III sound better than 40% fresh 722.6 spec ATF?
