For the Chryslers, that is what they ulitmately recommended - 30k miles. Then again, they use a synthetic fluid.
I need to change it in my Jeep, thinking about it. That has an Asian-Warner 4spd OD auto. Nice ride, actually. Shifts really nice.
Johnny - if there is a problem with that 6spd, check with Richmond ASAP, they have a good warrantee program, from what I have heard. I have also heard of some issues with those boxes failing... might be worth researching.
I know the 4L60 and 700R4 are essentially the same - the connectors changed, and I don't know what other revisions were made internally. That would take someone like Pete to address.
for the rest of the readers, the 4L60E is the electronic version.
Most think that the 4l60 is an improved version of the 700r4. This only slightly true. The 700r4 started in 1982, and was a piece of crap. The early versions did not even have a sprag, but a cheezy, weak low roller clutch arrangement. Anyhow, the 700 had a continuous amount of upgrades each and every year, up to present. Most of the improvements are able to be retrofit back to the early year units. GM did change the name in approx 1989 to the 4l60, but there was no specifice design change that triggered the change. In the vette, 1993 was a very transitional year. GM tried to make it share most of the same internals that the 4l60E was using. Most other gm cars were being fitted with the electronic trans for the 93 model year. The internal changes from 1982-1993 were numerous. Many dozens, possibly hundreds of revisions. I can almost name them all
