Mark,

I suspect John Wood knows how and why the bypass valve and tube works. He's a smart guy, and is only MIS-quoted here by some less-knowledgeable. I suspect he believes his trannys will never-again clog a cooler, and therefore finds them an unnecessary point for potential failure.

It's kinda' a roll-of-the-dice. If one clogs a cooler, one already has a big problem, and it's just a matter of degrees (pardon the pun) about what it's going to take to get it right again.

Early-on, I considered buying a kit to eliminate the bypass, but have since decided otherwise. It was your first-hand, expert testimony that turned the tide for me!

Mine's still there, still doin' its job!

Well after Mark gave me all the specs I needed to check to see what was going on as far as my cooling circuit. And after checking everything I don't have an issue with it.

But after installing the trans temp gauge from my motorhome. (Motorhome is no longer trapped under tree) I installed a Ultra Lite trans gauge and I don't trust what it is telling me. Mind you I have a E99 with NO radiator cooler and the gauge says I am running 125* after running down the highway after 30-40 minutes. But with my infrared thermometer I am 145*-150* and this with outside temps 75*-80*.

And I had to buy a new sending unit for the truck and the gauge worked in the motorhome and ran 150*-180*.

I find it hard to believe that it running at 125* and it takes about 15-20 minutes to get up to that.

Now Auto Meter got back to me and gave me this info to check the sending unit. So it either the sending unit or a trans case grounding issue.
