I have a '70 F100 that is getting a '95 F150 5.8L engine converted to carb and a '00 F150 4R70W with 2500 stall converter.  I'm assembling the engine with Dart 195 heads, custom cam, ... should get 400-450 FWHP.  3.70 9" rear end. 

My question is about what to do for transmission control.  I'm leaning toward the USShift standalone controller but looking for advice.  Thought about a manual valve body but would prefer to keep auto shifts.  The controllers currently go with a $75 discount but don't want to jump on that without some knowledgeable opinions.

Never been inside an auto trans other than to pull the pan for fluid/filter change.

Any thoughts or opinions?

Can't speak on their latest offerring, but my Baumanator works great.  You'll need to adapt a tps sensor to the carb.

Also, a stock convertor will probably stall at 2500 for you.  I'm getting 2200-2400 out of mine.

I've got a 4R in my LTD LX, using a Baumann (US Shift) controller. I really like it, and would recommend an aftermarket converter, the stock V6 converter is probably fine for most, depends what you want really.

Yes, need the TPS.  Bauman makes one that goes on a Holley.

The junk yard put the stock converter for my 4R70 inside the wrecked truck on the floor to protect it from the weather.  Too bad they didn't notice the windshield was out and rain water got inside the converter.  I bought a "remanufactured" one that is supposed to stall at about 2500.  Going to try it.

The truck is for street use with a few trips to the strip just to time it so not looking for excessive stall.

The manual for the conroller is downloaded and printed.  Will probably order the controller after I read the manual.

Thanks for comments.

Baumann is real good about answering questions, I've called there late on a saturday, thinking I'd leave a message for them and they could get back to me on Monday. Karl Baumann answered the phone, said he was just there wrapping up some stuff. He helped me with the questions I had and asked how I liked the product, and how it was working for me, super nice guy.

That's worth a LOT when I'm fumbling around in new territory.

I just upgraded to the newer one, so far I like it, plus it's got some features that allow converter clutch to come into play during shifts to help keep the RPMs in a sweet spot.

In what way?  I have an original, before shift us, now i've moved on from engine tuning to tweaking the transmission.  One thing when can't seem to get, or maybe by design.  When i allow converter to lock up in 3, maybe even tried second, seems no matter what I've tried, it unlocks first before the 3-4 shift, then relocks.  Have you ever tried locking sooner then 4th?

Yeah, I only lock it on 4th, it's supposedly hard on the converter to have to lock and unlock under load.

Have a Bauman Controller in my 69 Stang behind a 408.... Love it.

****Word of Caution--- Some Aftermarket Stroker Cranks are not compatible with the 4R70W Converters.... Apparently either the Pilot Hole on the Crank isn't Deep enough or the Snout on some of the 4R70W converters is a bit longer than others and Subsequently the converter will put excessive force on the Crankshaft Via the Pilot Hole and will Burn out a Thrust Bearing.... "Ask me how I know this"  *****
SO... if you are running a Stroker Crank, call the company that makes it or check their spec sheet in the tech notes and see what it says.... I found 2 websites that actually showed that several of the Eagle cranks are not compatible with what they call the Long snout AOD/AODE Converters "Which is same as a 4R70W" due to Pilot Hole Depth.... Now seems to me like that is the Crank makers Problem not the transmission converter problem.
So after burning a thrust I ordered an Aftermarket PTC Converter and followed the Shimming directions and it all seems Okay now....
I actually like the way the car drove better on the stock converter... It was tight on the bottom end like a normal car and flashed to almost 2800.... The PTC was loose as a goose the first time so sent it back and they made it like their 10" Nitrous converter which helped the Flash stall speed but not by much, and when locked in OD it pulls up to 2500 RPM @70 where as my Stock unit was 2100RPM @ 70 when locked in....400 RPM coupling loss apparently.... Not real happy about that... May send it back and see if they will give me a refund and drop a grand on a Continental :/
