US Transmission in Colorado?

[68converted]

Anybody use US Transmission in Littleton for the "Wildcat" upgrade to their AOD? I am having Tony do the work, and he sounds real inventive on how he rebuilds the AOD and especially the Torque Conv... The partial grocery list includes replacing all the valve bodies, hardened input shafts, adds more bands for a total of 9 wider bands, new servo, heavy duty sprag, on the converter- upgraded bearing, the fins are refitted for a higher stall (~ 2200) and the direct drive fuction is reengineered to work in all gears. Also, the torque multiplication is "improved" by a series of reengineering and improved flow modifications. Way too technical for me and I probably got it all wrong but it sounded impressive.

It's the same technology that he is using to produce the first Torque converter, 6 second pro drag car, of course toned down for street applications. Cost $1400. Reasonable?

Sounds like a pretty decent package, but I've not heard of the shop before. Maybe someone on www.coloradostangs.com has heard of 'em - post up.

Where in CO are ya?

???

that totally lost me.....

the AOD has 2 bands, low/reverse, and OD.....thats it.

he likely adds an alto direct clutch pack upgrade, which gets ya 6-7 clutches in the drum, never nine.

the input shaft upgrade is good, there is only one thats replaced tho, the direct shaft.... the forward shaft, well i have never seen an aftermarket forward shaft, doubt one exists...

only one valve body in an aod also, does he put a manual one in it ? if so, from who??
more likely he puts a shift kit in the stock valve body.......



1400, with a reworked stock converter is pricey, but about the going rate.
if they have an excellent rep, and that included R&R labor, gofer it.

good luck

(ohh, i would gow ith a 2600-2800 stall converter for any stock stand, modified, go even higher.......)

Like I said, I have no idea what is going on inside the AOD. What I listed was what I gleaned from our conversation. Let's just say the the conversation was a bit over my head. I did talk to one of his clients and he was blown away at how powerful the shifts were without being harsh. He has a fairly loapy cam and he has absolutely no surge in the trans at idle in drive. Absolutely smooth, was his comments overall.

We will see how it goes and I will let you know when I get it mated to the motor and installed.

Hmmmm.......i wish he would type it up, it is hard to understand what all you said, most of it doesn't make sense

replacing all the valve bodies - not likely, there is only one. Maybe he means he is installing an aftermarket VB.

hardened input shafts - awsome

adds more bands for a total of 9 wider bands - nope, only 2 bands and 6" is about all you can get out of them after you add there total widths.

new servo - great, i hope it is an "a" or "a+"

heavy duty sprag - great, I hope it is the MechOWC from the 4R

on the converter- upgraded bearing, the fins are refitted for a higher stall (~ 2200) and the direct drive fuction is reengineered to work in all gears. - awsome, you will have a non lock converter, 2200 stall is way too low, better negotiate a higher one.

the torque multiplication is "improved" by a series of reengineering and improved flow modifications - converter boost flow modification, very standard.

Not trying to rope the guy down, sounds like he knows what he is doing, but it is obvious (as you stated) that you do not....

Just talked to Tony, he said he could get me a list of what he is doing, w/ a parts and manufacturing list by Monday. I will post the list then. Thanks for the concern guys.

Here is the info on the Trans:
-Borg Warner High Energy friction clutches-forward, reverse, Intermediate, Forward drum modified to accept one extra friction clutch.
-Alto "red eagle" racing frictions with Kolene coated steel plates used in direct clutch. (Special 9 friction "Powerpack" offers 300% more torque capacity)
-Wider Alto "red eagle" racing band used for OD.
-New bushings throughout
-Heavy duty low and Itermediate sprags, w/ spiral lock intermediate sprag retainer used.
-Blueprinted front pump assembly w/ modified lube circuit.
-"Secret" valve body mods to improve upshifts, increase line pressure, and prolong transmission life.

For the torque Converter
-Refitted turbine splines eliminate direct lockup drive in 3rd and 4th gears; eliminated "chugging" (common complaint w/ AOD and a loapy cam.
-Heavy duty bearings, replacing plastic thrust caps on both sides of the stator.
-New heat treated sprag rollers with heavy duty accordion springs.
-Special machined stator and High stall impeller provide 700 RPM increase stall over stock.
-Turbine and impeller are furnace braced and hand tacked for strength.

Edit-hardened input shaft

Now, with that info... what do you guys think?
Thanks for the input
