i have just recently heard of a mechanical vacuum modulator for the turbo 400/350 tranys for blower /turbo cars or low vacuum producing engines.
however i cant find a single piece of information on this subject . yes i know there is a tranny form thread but on TC it seems everyone comes to the performance thread. so i posted it here .
does anybody have information on this mechanical vacuum modulator / more important does anyone run one that i could talk to . thanks guys.

check out http://www.transmissioncenter.net/350_or_400_high_performance.htm

scroll down to it.....#4X. 350 / 400 Cable Operated Modulator, no vacuum needed. This works well for superchargers and on diesel motors without a vacuum regulator. This modulator uses a 700R4 throttle valve cable. Cost $105.00

Hey, wait a minute.

Who was it that turn you on to that tranny shop, anyway?

Just givin' you a hard time. Glad to hear you found a builder that you were comfortable with. I really don't think the erotic. I mean exotic, modulator is necessary though, you should be fine with the regular vacuum one. I don't have a problem, and I have less than 5" at idle. I don't run a detent solenoid/switch (kickdown/passing gear), never thought I needed it.

Curious to which th400 you decided on. Like I said to you before, Chris seems to be the only one offering a forward pattern, manual shift, while maintaining engine braking.

There still is the little thing called freight. CK is further east than COAN and you are further west than I am. SOOO, expect shipping to be exceeding the 3 large nieghborhood. Sure hope that yours doesn't feel homesick, like my first COAN. Freight both ways and the weeks in between, makes for one tough pill to swallow, especially after spending a few grand on the tranny.

B & M brought them out years ago when they started selling mini blowers

why i got the ck performance from you rowdy. i was gonna wait to get the tranny home to give ya thanks for the help when i asked you for the tranny information . but i guess i can thank ya now and then again when i get it. after talking to chris we went with the stage 2 turbo 400 mechanical vacuum modulator as he felt it would be best on the clutches and bands as its a pretty accurate and reliable system. it will be a forward manual / auto tranny. the shipping charge isnt bad i will pm you on the cost.
