Can the BW 5 speeds be a good transmission? What were the problems and the any solutions? Were they a "rare" option and are they hard to find? Arerebuild parts available?

Thanks for any input,
Larry

I've broken a few of the BW T-50's; I'm not a fan. They were not designed to handle the torque of a V8, and will fail, even without abuse. All that being said, they seem to hold up behind a 4 or V6. Had one in a daily driver I used for two winters, a 1979 Sunbird V6 wagon. The across the gate 1-2 shift can be awkward and easy to miss, especially in "spirited" driving. I used to pull away in 2nd, unless I was on a steep hill. Only other vehicle I ever saw with the same shift pattern was a late 60's Porsche 911.
The T-50 is not all that rare(or valuable), just "different". They also require a unique trans crossmember, driveshaft and torque arm if you're trying to swap one into another vehicle.

Some T-50's had the problem of first gear seizing while in another gear, not really welcomed, especially if you were in fifth. Determined to be a lack of lubrication to the first gear roller bearing. Cosworth owners overfill the trans about a pint. We have a member that rebuilds them by adding a bronze bushing in place of the roller bearing.

That overfill idea probably would have saved the last one I broke. Long highway trip(800 miles return), passing cars without downshifting(lots of torque from a 400 SBC and 3.42 gears). It started popping out of 5th gear about 200 miles from home, and very quickly deteriorated into no overdrive whatsoever. It was the original trans from the car, and I left it in there after the V8 swap, specifically for the road trip. Replaced it with a Saginaw, and that lasted fine, even though it was a 4-cyl one with the steep low gear.

I've busted 3.... all behind a 3.2L V6 in a Vega that was driven hard.
They are weak, as mentioned above. They were offered behind the Olds 260 V8 for a very short time (a few months).... until they realized that was a bad idea.
The odd shift pattern is sometimes called a "road race" pattern because the 2-3 shift is more important than the 1-2 shift on a road course where 1st is usually only used in pit road. Shifting straight up/down for 2-3 is much easier. This was found in 60s European sports cars.

That being said, I like them. I've had one live behind two 215 Buick V8s..... but they only make 240 lb-ft torque ... and in a light Vega.
1st gear is a low 3.4 ratio that works great with a H-body's short 13" wheels/tires and tall gearing. I run a 2.56 rear gear easily and regularly pull out in 2nd. Overdrive isn't huge at 0.8 which also works well with tall gearing and short wheels/tires.

For the money to rebuilt one, I'll probably go with a T-5 when my remaining two T-50s blow.

Dwight that pattern is good for the snow too, as 1>R is more important for rocking your car out of the snow! Way easier than a1>6[th] position for a rock to get you out. Usually lose all momentum before you can complete the shift and end up sitting still for awhile! We won't even talk about Reverse with a "Lock Out" Harry

Now come on Jeff you are about 20 miles NORTH of me, [+/-] and you never considered that. I take it you haven't been stuck in the snow in your buddies 4 Speed with that over to the right and down pattern and he never drove in the snow before with a stick YEP he got 'er all glassed up for me to get it out. You should have seen the look on his face when I put it in second and let it spin, climbed out and pushed! You have to be fairly certain you can catch the car before..... Well you get the pic' Harry :pook: :canada: :canada: :beer:

Having had a winter beater with a T-50, I will admit it was easy to "rock" out of a snow bank with 1st and reverse close together with no lock-out. A real pain with a Saginaw and an OEM H-body shifter.

Harry, I am a firm believer that our local weather systems pick up 100% more moisture when the travel SE and cross the Detroit river before dropping all that "river effect" snow on Windsor!

I am not debating the advantage the T-50 shift pattern has over a Muncie or Saginaw 4-speed, I have just never considered it. I never drove H-bodies in the snow, I was a late converter to the H-body world, I always drove GM A & F bodies when I was a Kid, so I an well versed in rocking the bigger heavier cars out of the snow. But I have never driven any of my H-bodies in the winter.

I remember driving a ferrari that had that first gear below reverse back in the 80's, it had a steel gate pattern so no guessing what gear your in.

I think that Ferrari used to pitch the ease of rocking the car when stuck in snow drifts as a selling point. :rolleyes: :lol:

Jeff I did my first one for half the winter walked the rest of that one if it was snowing! Pure :censored: :cuss: in the snow! So how about rocking it out of that mud puddle you parked in? And you are old enough to NOT be out "Parking" :dance: with your Woman! :lol: Harry :D These are "Extremely Traction Challenged" cars! :burn: :burnout:

My first H-body WAS my winter car. :lol:
With a pair of C/78/13s on the back that sucker would damn near go anywhere. :mrgreen:

Mine was a '76 HB with 4.3L V8 THM250 Vredestein's probably the same as yours BR78-13 medium tread depth just wouldn't move in the snow but it sat real low, even after the spring change. :? Harry
