REVERSE - 64 - 76
DRIVE - 45 - 63
SECOND - " "
FIRST - " "

How and why did I miss this?

Igy, man I am so sorry. Really I am! I should have known that if your pressure was that low, although border line, once your TC stalls - all hell will break loose.

This is why I am beating myself up here...

It is a known fact that the CD4E is very sensitive to line pressure and changes in line pressure. It is its second short fall. Knowing this, along with the fact that "I" missed this information that Igy posted... THREE TIMES none the less, I should have mentioned the pump to begin with.

Igy, my deepest apologizes go out to you. I feel like I have let you and many others down. As a moderator of this forum, I should have paid more attention to the thread and seen this, but I apparently didn't and missed it.


Now that that is out of the way, may I suggest this. It might be worth looking into. I'm not sure how much a pump is, right off hand, but these pump gears just might help you out since you have put so much into it already.
