Good afternoon,

Did you replace the transmissions with new or used?

What were the issues with the transmissions?

Okay, what about the other times?

Did you have the TCM flashed?

Are there any codes?

New, and they put a bigger cooler in, as well. No that's the strange thing, a code came up to replace the gas cap but my mechanic found the shavings in the fluid again so back to the transmission shop.

Someone said maybe it needs a software update? Have you ever heard of that?

Okay, sounds like you need to have the lines flushed out. If they did not flush the cooler correctly, the metal will get into the replacement transmission.
