Every manual valve body has something saying RACE ONLY or NOT RECCOMENDED FOR STREET USE. Why is this, just because of the harshness of the shifts or what? I have my eye on this one http://cgi.ebay.com/ebaymotors/MOPAR-Tor...eQ5fCarQ5fPartsI already shift my 904 manually because I dont like the shift points and the 904 kickdown just wont adjust to where I need it to be, shifting it is not a problem as I like to shift it myself (haha I really wanted a 4 speed!). Im swapping to a 727 and dont have a kickdown for it, this wont cost that much more, and if I didnt do this Id be installing a shift kit for hard shifts so this will probably cost less than the kickdown and shiftkit would together. Opinions?
Now I need to pin those needles, got to feel that heat

lawyers.
if you got into an accident because you didnt shift right or it made you go sideways when it hits second, someone might sue them

alot of racers drive on the street with manual valve bodies...
as noted above..just a disclaimer to protect the manufacturer...
one thing with a no low band apply valve body as this is...if you are in 1st gear and coasting..do not floor it...

I have driven my Trans Am with a manual valve body for over 25 years. On a car that is not an everyday driver it is not that big of a deal. I found it to be extremely fun and often folks thought I had a stick. I will have several cars set up this way when I get done but my only suggestion is if you have more than one car setup manually, use the same shifter in all the cars.

The e-bay offering is the oldest and most basic design reverse manual VB; the main reason they are not recommended for the street is that, with the lack of low-band apply, there is potential for damage when the ill-informed user abuses them. (like in the example 70AARcuda mentions) The newer design VB's have low-band apply with a check ball in the rear servo circuit to mitigate harsh downshifts to 1st. The VB in the link below is the best/safest design available for the street: https://www.coperacingtrans.com/product_info.php?cPath=23&products_id=67

i got the Transaction Cheetah Manual/Automatic forward shift valve body. It works like an automatic shift but will kick down whenever you want. You still need the kick down linkage.
I believe it is a low band apply VB as it engine brakes in first

HAHA GOOD TO KNOW ABOUT THE COASTING THING. I do this ALL THE TIME with my low band apply 904 and man when I do it the car JUMPS AND GOES. Ive convinced alot of my buddies the car has good power just by accelerating normally until I get the engine up to 3500 or so and coasting until its around 2500-3000, step on it and it kicks HARD and its just a 273. Doesnt keep pulling after 4000 though so I just let back off and go into second driving normally. Lots of people go "HOLY S*** THIS THING PULLS HARD" but its just the deception. I will miss the hum of first gear when I slow down though, it just sounds cool!
Does the manual valve body mean anything different for the sprag? The transmission is a stock 727 out of a '72 340 Demon, is it okay to just put the manual valve body in? The car is going to have maybe 420 ft lbs of torque max and 370 horse, more likely 350 horse and 400 ft lbs sure grip rear end, and not too much tire, probably 225/70/15s.
Will this VB work okay though? Im not looking for max transmission performance, just good performance and some fun. Its a street car I might hit the track this summer once or twice just to see what it does, but its a '67 Satellite and if it runs mid 13s on street tires I will be happy with it for now until I have the funds to go big block. Im working with a budget of about 500 bucks to get the engine backtogether, after my cam, lifters, and valve springs im going to be left with about 250 for the transmission.
Im just trying to get the thing to be daily driver reliable and fun, and I drive it literally every day unless there is snow/salt on the road. Right now the 273s got some carb issues and the 904 works alright but had a leak, the engine leaks from a few spots and looks like crap. I just want to be able to hop in and go and not worry about the carb hanging up and flooding etc.

i have a turbo action cheetah reverse manual in both of my drivers. love them. acually makes a car easier to drive on icy streets as you can take off in 2nd and leave it there, and not have to worry about an upshift breaking the tires loose. as mentioned above, do NOT floor it when you are coasting in low. NO getting in and out of the throttle in low. you could damage the sprag,which could explode the front drum,which will destroy your transmission,damage your car and maybe damage you.
I thought that's what the cheeta pro street forward pattern mvb's were supposed to prevent. They specifically say those ones are safe for street use.

Just curious but I have a stock 904 transmission behind a mild built 318. Will it hurt to not use my kickdown linkage with it and just shift manually all the time?
Yep, you'll burn up your transmission just as quick. Either leave it auto or install a mvb intended for street use and use it as directed.

I run one in my Charger,,,street car,,,and love it,,,,sorta like driving a stick,,,,,and i can shift it when i WANT,,,as opposed the car shifting when it thinks it should,,,,
no issues,,,except as mentioned above,,,have to be careful in first gear,,,,
If the tires go up in smoke in first,,,i usually pull it to second gear,,,instead of getting off and then on it again in first..........

yes, you are correct. the pro street forward pattern is low band apply. i have the old reverse pattern no band apply. the ebay link gtxmatt provided is also no low band apply valve body.
