Mercon 5 into a rebuilt E4OD??

[Noiseydiesel]

Getting the trans rebuilt with a Tugger kit and all for the engine swap and wondering if Mercon 5 is the desired fluid for an upgrade at time of rebuild?
Meanwhile Promar called and the engine is ready.
Now waiting for the rest of it after the left knee replacement December 23rd.
Merry Christmas!!

@saburai asked the same question when we did his and the general consensus was yes. Pretty sure that's what we used when we filled it.

It will be interesting to see what you think of Promars engine when you get it in. I thought about getting one from them in the past.

Promar sleeves the engine block and that is a good step in the right direction. Everything else around the engine will either be new or rebuilt. I figure to get this all done around mid to late January. Now if Diamond Eye exhaust built the system as I requested, a section of the down pipe will come up when the engine is pulled.

I spoke with a few very knowledgeable auto transmission guys and as @chillman88 said, the recommendation for the e4od is Mercon 5 is . It was suggested that changing the fluid more frequently would offset any benefit of running a full synthetic fluid. Furthermore, they stated that at the temperature that the e4od operates at synthetics temperature resistance isn't really needed. They also brought to point that the more modern automatic transmissions run at a higher temperature and therefore the full synthetic is required.

A short history lesson I found out from Lubegard. If your old enough you remember that vehicles up into the 60's didn't require transmission fluid changes as a rule. Fill and forget was the rule. Then eventually the whale oil additive was longer available and suddenly in the 70's transmission services became the rule.
LubeGard came out as an additive to put back in what was removed by the whale oil additive that was no longer being used.
A few more years and synthetic fluid has made it's way onto he scene and now even LubeGard is becoming less used in a lot of applications.
This trans will get a two quart deep pan and the transfer case will add another two quarts to the mix.
So 4 more quarts on top of synthetic oil, I would believe this transmission should run fairly cool under most conditions.

FYI - The transmission and transfer case DO NOT share fluid. If your transmission and transfer case is exchanging fluids, you have a couple failed seals that need addressed.

Ya' know. . . I am starting to feel like that yella' fellow above. I figure, without looking, I am about going on $14K in financial fun in under 3,000 miles. Not including the original purchase price.
However, this sun beach better run for 15 years plus without much of anything else done to it.

This truck is starting to remind me of a country song somewhere.
