Allison Filter Problem

[TRPSHOOT]

I was on a shooting forum and there was an off topic post that I thought you guys could help with. This might be smack but here it is, the following is a cut and paste from the thread.

"Seems that many of you guys run trucks with the Duramax/Allison combo. I've heard a few horror stories of the oil filter getting broke off with some very mild off road use. The filter hangs down with no protection! Do any of you folks know of anybody making a skid plate for this application? Thanks much."

Post after some people challenged him about never hearing of this problem before . . .

"I am a Chevy guy thru & thru. I know of 2 people personally that this has happened to, and talked to many a tranny shops, and they all haveheard at least 2, 3 happenings. The problem is that when this happens it will break the tranny case. The threads are part of the case, not a bolt on replacable part, like on an engine spin on oil filter."


So any truth to this? Have any of you heard this before?

According to this guy using his math that would be 2 people with many tranny shops knowing 2-3 incidents, that could easily be 10 just that guy knows.

I did a search and could not find any posts about broken/torn off Allison filters . . .

Thanks.

I posted on other thread, but I don't think as many people look at that.

Never ever heard of it happening. The Ally filter is very thick can and it's a very short unit that is well above other items surrounding it such as the tranny pan, support member, torsion bar, etc. I'm calling BS and suspect it's the new "melted aluminum head" (since that one finally fell deaf!!)

For that to happen you would a lot of damage other places as well. I have never heard of this till now. If it was and issue you think it would have come before now.

lift the truck than no problem.... actually chevy does sell factory skid plates , just order from thew dealer.

When an Allison tranny is off the truck and sitting on a pallet, the spin-on filter never touches the pallet. It rides above the bottom of the factory Allison pan.

Now, I have heard of a piece of road debris flipping up and taking out the transmission/transfer case wiring harness.
