A little confused. Are you asking what an E-prom is ? It's the "chip" that goes in the ECU for the engine. E - means it's flash programmable (can be changed by someone with the equipment and know-how).

My transmission is all sorts of ****ed up confusion right now. I'm trying to determine what vehicle/engine this eprom was for. I found that sheet that had a couple numbers and corresponding engines on it, but this number was nowhere on it.

From what I can find the chip is for the engine computer. This shouldn't have any bearing on your transmission if the engine is operating properly. A little more info if you could :

What, exactly, is wrong ? You asked about an engine chip then mention a transmission problem. Diagnoses are based on facts. If all you wanted to know is what the chip is for, then you have your answer. Glad to help but need to know what the question is before a suitable answer can be provided.

Total mea culpa, I misread what this fella was looking for. For posterity (we sorted it out on his other thread about the same thing ) The CORRECT ANSWER IS A FEW POSTS BELOW.

No, this is the program chip in the transmission computer. We don't have an engine computer in our HMMWVs unless a non-military swap had been done. I saved an extended list of EPROM chip numbers on my desktop. I'll try and find it and give you an engine/trans combo for this chip. I'm also wondering if you have the correct torque converter, as that could really mess with what the TISS is reading and thus, your shift points. When you're limping in first gear, do you have to get to a rather high RPM to start rolling/feels like slippage?

Thats very interesting as I took that EPROM chip out of a Transmission Control Module for the 4l80e...

Definitely is the correct torque converter, came with the transmission. I disconnected power from the TCM to see what true limp mode felt like. Its definitely starting out in 1st gear, cause 2nd gear is a lot more sluggish.
I DID get the tranny from predator... which is a **** show buying transmissions from those guys...

94 6.2? That's interesting considering the TCM box has the number for a m1114... I got the tranny and tcm together from predator. I'm near the end of this 4l80 change and its brought more trouble than I thought it would.
Its also interesting cause thats exactly my vehicle, but the box did not come with mine...

Well that makes me feel a little better.
I'd rather have the problem be in one of the sensors rather than the computer.
I believe the chart of computers and proms listed anything after 2001 to be interchangeable.

Posting a new thread with a few numbers and no questions, is not the way to get help. It just confuses others and clutters up the forums.

I'm not going to take the time to make sense of your other 6 threads and merge them in an order that would be understandable, so please just continue one of your existing threads the next time you need help with this transmission project.

Do you have a sheet to cross reference the numbers and the truck engine combo?

Okay, will consolidate in the future.
