where is a good place in Melb south east suburbs to get a 3 speed glide?.......how much roughly should l be looking at? cheers

3 speed c4 u mean?

Th400

yeah, wna know is the c4 as strong as the 2 speed power glide? any what would be roughly the price differences and a good workshop to go to? ---------- Post added 01-08-11 at 13:39 ---------- cheers bro.

First gear seems as if you've begun in second gear in a three speed and top gear is the same as a normal three speed top gear. Not many people with big power can use 1st gear on the street any way so there's not much point having a real short first. Well summed up!

Powerglides are alot cheaper then a full house c4 and are far more reliable. Plus there is endless amounts of aftermarket parts available for powerglides so upgrading later on is not an issue

moved to the right section

Maybe the 3 speeds cost more because they have more parts to be strengthened. Having an extra gear in there. So more clutches etc.

So more clutches etc. Yes that's exctly why and they take longer to prep and build.. As for what I wrote b4 it was a joke at the 3speed power glide.. Some original photos have not been recovered yet.

if a 1950's 2 speed tranny was any good for the streets at keeping an engine in its powerband we'd still use them. I can see the benefit in not spilling your coke after a drive through but really....(don't get a manual valve body if you still like 'D') to accelerate any mass using the full 30.49% efficiency of your petrol engine, it will need to stay on power band. more gears make this possible. http://en.wikipedia.org/wiki/Powerglide

I believe everyone is referring to driveability and strength in this discussion.

yes, my point. unless this is specific to transmission drivabilty. I look at the whole vehicle when making a decision like this. the occasional drag racer wouldn't benefit from a 2 speed, nor the regular street driver. as for strength, naturally a box that starts off in a higher gear won't transfer torque as high as a 3,4,5,6 box etc and therefore seems unbreakable but one would find if the equivalent torque was really transferred through the gear train in the equivalent ratio it may well show a completely different side.

We're not talking equivalents though, we're talking actual boxes. The occasional drag racer or street car may not benefit from a powerglide for 99% of its driving but will put up with it because it works for its intended purpose - racing. While in theory you may be faster with a 6 speed auto it'll cost a lot of money to get it to handle big power when a simple, cheaper and stronger option would be the 2 speed powerglide.

High Stall Converters will help with having a lower number of gears - keeping the motor in its "peak" torque/power range. Standard cars do not do this because of a) fuel efficiency would be out the window b) keeping a gearbox cool with a large stally is more difficult/costly than standard and c) average mum & dad driver won't put up with just 2 gears and a high stall. Highly modified cars that make peak power, and have alot of money put in them - more than likely the owner is not concerned about fuel efficiency, or only having 2 gears - as long as it goes fast and isn't a complete pig on the road. Less gear changes can make the car faster - *IF* set up correctly.

I see what you mean bachig24u about strength, but find me a trans that has a standard factory planetary set as big and strong as a pg and allmost endless amount of parts and upgrades available. They have had 50 plus years to develop it, compared to newer 4 5 6 speed boxes. I think compared to a 3 speed there isn't alot of difference street driving. An over drive box is better obviously but to get any thing good you have to hand over a decent amount of coin for some thing that won't be as reliable as a powerglide.
