Even when left in Drive you'll still feel it kick sharply into each gear and change quicker.

I dont think you can get the BW35-40's with the shift kit. I tried b4 with my XE and the guy basically said, get a 6cyl c4 instead and do it to that! The BW's cant take it for some reason. I hear you can get the stock converter re-stalled though!

shift kits are available for the BW30-50's but are hard to come across, they are able to be made into a rather strong box, but the information is hard to come across, and not many auto reco places would bother, when a C4 is easy to come across, easier to work on, and easier to stenghen, and is already a lot stronger than the BW's

how much power can u put through an auto before a shift kit is required

and does anyone know much about the "power glider" transmissions i think thats what they r called me mate reckons he is puttin one behind his 351 cause they use less kilowatts than a manual and auto in gettin the power from the engine to the rear wheels

I would only recommend glides in true drag racing applications, but yes, they do use less power than conventional autos plus they can be rebuilt to handle a huge ammount of power. Once again, they are hard to come by. I hear C4's are good for up to 400fwhp in standard condition before any mods are necessary. Generally you see C4's rebuilt with h/d clutches and bands and perhaps a B&M st2 shiftkit put thru it. That will handle ample ammounts of power (300-550hp) without too many hassles at all. (Those in the know, please correct me) Depends on application though!

Well a glide should well and trully handle that much power. I hear they arent cheap to rebuild though. You would be better off ringing a few speed shops close to your area for a possible chance of picking one up.

My mate is doing an 800hp 351 stoked windsor in his 67 XR which he hopes to pull high 9's out of in full street trim, and he is using a glide with a 4500 TCI converter and race bands billet input shafts and the works. Its set him back about 5k for just that :AAHHH:

well that is quite funny but ahh about the price cause me mate is wanting to put a glider in his 67 XR falcon 351 in street trim but he is sticking with the C4 for now but by the sounds of it using a glider would be a costly job but thanks for ya input

It all depends on how much power your wanting to put thru it. The car is as strong as your box can handle. C4 will always be sufficient for street/race applications. But a glide is better for all out race and can be built to handle massive amounts of power! Its all up to your real application, and of course, how much $$$ you have!

ive got a c10, and when it changes gears, the wheels chirp. also, when i change them manually, it is really quick and rough. does this mean it has a shift kit?
