tranny cooler too small?

Man,
All this started just because I was trying to decide if the transmission cooler I bought was going to help or not, and I'm still not sure, but I'm going to use it anyway.

It should help, be better than not having one at all.  It's a little on the small side. IMO.

As long as the tubing is the same diameter or larger (doesn't impede flow), and the fluid still goes through the radiator loop first, then it can only help.  IIRC, you are not towing outside your tow vehicle's normal rating, so it's more like added insurance than a requirement, even if it is small.  

If the manufacturer says you MUST install a tranny cooler to tow a trailer the size of yours, you might want to upgrade.

The 1st page of this thread answers your question about as specifically as you can get.

I don't think that it would be wise to take the advise of anyone giving you a definite "Yes" or "No" answer.

We try to supply as much info as possible to make the decision yourself. If you need any further explanation of one of the specific posts that give you information, please feel free to ask. If it isn't clear to you, it probably isn't clear to others either......sorry about that.

Basically, the physics behind the trans cooler are that the cooler that you can get the trans fluid the longer your transmission should last. The hotter that the trans runs, the shorter time the trans will last. It's just as simple as that. You just simply won't know if you made the right decision until you find that the fluid is getting burnt or not. :sombraro:

The exception (there always is one) would be if you live in an area that gets extremely cold.  If it gets cold enough to make the fluid thick, you can destroy the tranny with too much tranny cooler.  I don't know the numbers, but I know it's not that cold here, and it gets to -25
