The shot gun cooler, from KC marine, takes up a lot of space in the trans fluid reservoir of the Merctrans. Should I still try to use the specified quantity of fluid or only fill to the full mark on the dipstick? I know that I cannot consult KC marine any longer, so I'm hoping someone here is familiar with this issue. Thanks.

Thanks. I wouldn't like reducing the amount of fluid.

I was considering a remote cooler option and adding volume to the trans fluid.

A temp and pressure gauge are also a good idea.

I heard that upping the pressure helps a lot.

The trans pump also has issues. Is there merit to having an external pump, that also cools? Also adding extra capacity at the same time.

I was able to find the old KC Marine website on Wayback Machine web archiver.

There is a lot of good info on there about how to treat the Merctrans, and how to get the most out of them.

Are you able to find actual web pages on the Wayback website?

is kc no longer in business. he did a tranny for me couple years ago with the gatling cooler and did a great job.i was gonna have him do another tranny for me for my carrera project. I've been running the lucas marine full synthetic atf that kc recommended with no issues. if he's no longer in business who else rebuilds the merc trannies.
