> Corley, from reading your latest post, it is obvious that you do not know precisely what Manny does to his transmissions, ( nor do I). and you probably have never taken up a conversation with him, so I suggest you follow suit and save others from forming wrong assumptions.

We had the opportunity to watch the amazing Manny rebuild our tranny (while trying
desperately to stay out of his way). He did the entire rebuild, including pulling and resinstalling,
in the course of a single day. Just watching was exhausting. I really wish I was more knowledgeable
so more of what he did could have soaked in, but here are my notes from the time:

> He does lots of his own touches -- adds another clutch to 1st gear, uses all stainless fasteners,
> puts in a much more robust sprag(roller?) clutch thing with about 3x as many rollers in it, and
> slightly bends up the tabs on the first clutch plate so that even if it wears all the way through
> it won't spin. All new bearings, bushings, clutches, gaskets, torque converter, etc.He uses viton o-rings
> because they're good to much higher temps.

> He taps and plugs the passage hole for the kick-down switch function. He
> doesn't like the kickdown because it steals pressure, leaks, and causes slippage.
> Says you still get downshifts due to vacuum and you can always downshift manually so not needed.
> He does install a new kickdown, but only because he has them and it fills the hole.


I'll add that anyone who has ever dealt with Manny has gotten an impossibly good deal.
All that great stuff he did to our tranny, plus a 3.5 chain drive, was far, far less
than what a local shop charged us for a common ford van tranny rebuild. Manny is
generous to a fault and a mechanical genius.

just my .02.

Amen.

I guess you weren't around long enough to become skilled enough to torque
your own pan bolts, huh? :-)

Called him today to order 1-Ton for a friend. "I'll ship two so we'll have
a spare over your way."

If the above two posts are aimed at me (can't tell from reading the, but my name is in there), please, pay attention to what I wrote, and don't change it's meaning.

I am trying to clarify if in fact Manny does not recommend down shifting a DFCO engine coach. If he is recommending that, I believe that may create a dangerous condition on steep docents. The stock brakes are not up to stopping 12,000 lbs over a long distance, on a steep incline, period.

All I'm after is clarification on Manny's position. None of the posts so far has clarified that particular aspect of Manny's statement. If you are running a QJet, this question does not apply. If you are running stock GM TBI, this question does not apply. If you are NOT running EFI with zero fuel being metered to the engine on a decent, this question does not apply.

And finally, why is it that I continually seem to be misinterpreted in things that I post, then accused of being ignorant?

Ken,


I may be able to find a home for that kit as I will some front end refreshing on the Birch. Do you know what Manny's kit goes for and what else needs to be purchased?

Thanks,

Joe,

Not to be uncooperative, but the spare kit is meant to be just that: A
spare immediately available for anyone in the area with an immediate need.
If you forsee the need for a kit, call Manny and arrange for it to be
delivered directly to you on the schedule you need.

I don't know the current price since Manny varies it dependent on his
current costs, but I expect it to be around $1500 plus as much as $300
shipping from W. coast to E. coast (we got the first 4 shipped for <$400
though).

The only additional parts required are the calipers and pads -- it would
make little sense to ship those across the country.

Oh you guys and your silly use of capital letters. When talking with Manny
about this ability of the computer/ebl/whatever you want to call it to
lower the rpm of the engine to a point that that (lowering the rpms of the
engine) and the inefficiency of the torque converter at those really low
rpms allow the pressure going to the bands (I think he said the front one
but I'm usually wrong) to lower to a point that it (the lower pressure)
cannot hold the band in tight contact with the drum. It's this slippage
that Manny is worried about when one downshifts while coasting/decelerating
with low fuel going to the engine. That's what I understand from Manny. If
this explanation seems unreasonable or if it's not clear (it was enough for
me as I have the efi but will never have the ebl/DFCO/or whatever) then
just call Manny. I have never seen him too busy to answer the phone and
talk to anyone about anything (except maybe Deo). And, as usual, this will
be my last post on this particular thread as I have nothing else to add,
but it is entertaining to some degree so I'll keep reading it.

Ken,

No worries, really.

Thought you were looking to move the kit. I will contact Manny when it is time.

Thanks for the info.
