if i remember correctly he suggested not to switch from shell la 2634 to esso unless you rebuild the tranny. he shipped me my 5hp30 with esso.
it is 1 year & no problems except a tiny leak aroung the shaft connected to the shifter cable.
i will need to call him about it before my warranty expires.

Tim,
The shifter seal is a DIY. Jaggi has the part- it's like $1.50 for 4 of them. It consists of a black rubber washer looking thing, that is pushed in around the shifter pin (remove the shift lever and it reveals itself). There's one on the other side too, as the rod goes all the way through the case.

Kirt showed me how to do it. Removal consists of using an awl with a curved end to pull that little seal out. Extreme caution must be used not to score the rod, or else it won't seal properly again. You dont have to be a surgeon though- I did it with a curved needle for stiching leather that I got out of my wife's sewing kit. Installation requires a way to push it all the way back past it's flange (it's countersunk about 1cm into the case. I used a piece of tubing that had an interior diameter that allowed it to slip onto the rod, but an exterior diameter narrow enough to get it into the hole. If you use any thing else to poke it back in, be careful.

Unfortunately the cause of this problem (imho) is Sports mode. At least in my 5hp30, I've done it twice, and both times I noticed the leak after driving the car very hard in 4 for awhile. My case bolts, torque converter, and output were all dry, but I had weeping from the shifter seals. Somehow pressure builds up, and pops the seal out of it's seat. Then you lose fluid very, very slowly until the typical low fluid symptoms manefest.

Call Kirt anyway just to make sure I'm barking up the right tree.

Same with you MBXB. Kirt is the source of all knowlege. Jaggi too, but he won't tell you much about doing things diy.
