Thanks for the replies of our previous thread, on the hesitation trouble on a 4R/70W full electronic tranny. We are about to replace the fluid, by removing drainplug on converter, but does the tranny need any flushing, and if yes, what kind of product to use.......??
Awaiting your kind answers, Mike Versluys

I do not know the transmission under discussion (and resisting responding to the "tranny" reference :buck:), but generally you need to drain the case and change the filter (this is more important in fact) rather than just the converter.

Hope this helps.

Regards,

Bob

As for fluid, the 4R70W will develop a converter shudder unless Mercon V fluid is used. Wouldn't bother with a 'flush', just drop the pan, replace filter and drain converter if possible (converter drainplug was eliminated around 2002 as a cost-cutting measure...)
