I just put a replacement e4od in and it drove fine for a day, and shifted fine in all gears, but idled rough and so I spent about thirty minutes trying to troubleshoot the idle and when I went to drive it away, the trans would not engage unless the rpms were up around 3k!
No codes, trans fluid level fine, speedometer works, brake lights work.
What could it be?
Please help!
I'm tempted to just use this thing for target practice.
i guess you might as well shoot it since you've already set it on fire ....
i'm sorry, i'm no help at all.
was this a used trans you installed?
nothing good makes it not engage until the rpm's are that high.
if i were guessing, i'd say #3 was bad before you installed it.
any kind of warranty or exchange possible?
if going to the trouble to install an unknown transmission, i'd seek out a transmission shop with a dyno that can verify that it is a good trans before installing it. most bigger towns should have at least one shop with a dyno if you call around.
Have you replaced the coolers with each transmission? If not, when you install trans #4 it's going to fail, too. Bits of the old transmissions get caught in the coolers to be slowly released back to the trans, causing it to fail, too.

If it wasn't dead at this point, 3000 RPM to make it engage certainly killed it.

Something mechanical broke. It could be a seal, the pump, or a part of the rotating assembly. It's impossible to narrow it down to the exact part without a teardown.
