Switching to a 16197427 to run a 4L80e.

[racprops]

A major question:

Switching to a 16197427 to run a 4L80e.

My read is I can get any 7427 and just reprogram it, is that right??

So can I just load the basic operating system for a 350V8, for a 4L80e.

OR do I NEED to get a 7427 from a truck that had a 4L80e??


I can find 16197427s everywhere reasonable BUT no one can tell me anything about the van or truck they came out of.

They cannot tell me what transmission, engine of even if it was even running when hit.

My old friend who had a junk yard would often say when asked if a part was any good, “Well it was moving when it hit something.” He could then show you to car or truck it came out of. Sadly he passed 7 years ago and wife sold yard.

why not just have blackbear or someone similar burn you a chip with the correct programming for the engine/trans?

You can look at the BCC on the chip and see if it's for your combination, or have someone burn a chip with the associated BCC for your PCM.

Here's what to look for, yours probably looks like the one on the left.

You must be registered for see images attach

Then find the one (with engine, trans, and rear end) you need here,

Or here, something like BJDR for a 5.7L with 4L80E. A lot of vans had the 4L80E matched up with a 5.7L
