hey all,
i have a friend who wants me to install my 1.76 planetary in his 1.82 powerglide,his transmission is a rear pump model.
I know he will need a tailshaft huosing,and a different input shaft...but I'm not sure about a new drum and governor support,any help would be appreciated

If this is a race car application with transbrake?

The gerset will interchange without issue. The rear pump can be trashed. Why would you need a differant tailshaft?

hey Jody,
The output shaft on the 1.76 is longer than on this 1.82,so it will need a longer tailshaft housing.... there are two different length tailshaft housings for a powerglide,as well as two different length input shafts,also the high clutch drums from a 1.82 and 1.76 are different depths internally but I'm not sure if they are the same size externally,and i think the rear pump or gov. support is where the support bushing for the rear of the output shaft is so I think that something has to be there.

I have swapped out my 1.82's when they broke and dropped the 1.76's right in with the same tailshaft. I know there are some oddball glides out there but the ones I have dealt with will interchange. I didn't get a differant clutch drum either, I only run the 5-clutch pack too.

Is this a core your building that is all stock? What is the plan for this glide? HP? There are differant lenght out put shafts, use the 14 11/16. As for the input drum the big differance is the inside depth. Short and tall, either one will work, just depends on how many clutches you want. Go with a after market input shaft and your good. Are you going with a T-brake , Manual V.B. Or a stock set up?

The 1.82 he has is the short output shaft,coarse output spline (16 splines I think) ,rear pump. This trans. with the existing output spline cannot use the aftermarket yokes available which limits him to a 1310 series u-joint,plus the gearset is weak.
My question is:
1) the drum normally found in a 1.76 gearset powerglide has a 1 7/32" inside depth,the drum normally found in a 1.82 powerglide has a 1" inside depth, is this 7/32 difference also in the overall height of the drum?
2)when removing a rear pump what needs to be done to seal/ support the back of the trans.- are there any modifications that need to be done to the valve body?(factory valve body)
3)the 1.82 gearset has a captive thrust bearing the 1.76 has a torrington,are the overall installed dimensions the same?or does a difference in drum height show up here?

1. The drum is only different on the inside depth, you can use either one.
2. On the rear pump case, it was drilled different for the reverse apply. Are you using a T-brake, manual V.B or Stock (Auto Shift) ?
3. The only differance is in the input shaft use an after market one and it fits both gear sets

Matt I spoke with Jeff on the phone about this Saturday and it's a stock valve body tranny, no brake or even a manual valve body conversion. I'm not qualified to say what will and will not work with this and I told him to contact you as you may have dealt with one of these in the past.

Me, I've built a couple of dozen of these over the years but the all got manual valve bodies with Tbrakes so I just junked the rear pump crap and machined the high gear piston for whatever clutch pack I was using at the time.

Seems Im in need of some info on this also.just measured my (stock)glide input shaft and it measures 12 5/8 lenght.Isn' t this a 1.82 gearset?A 1.76 (stock) input shaft measures 12 7/8?... Thanks...Also wonder if I should find a 1.76 gear set..and not even fool with the 1.82?Friend ran a 1.82 gear set for a coule of seasons before it broke,2800 pounds and 6.8's 1/8.whatcha think? =;

I ran one in that first Camaro I had and it went two years before it went south. Broke it at Piedmont Dragway. Also have broken three rear gears at that track? O:) Yeah, that track HOOKS! =;

Barry has a 1:76 for sale in a bundle of stuff that you might talk him into separating out for a "buddy"! :-k

I ran a 1.82 for the better part of year. It broke 25 ft off the line when I was down to 8 cars. It cost me a a shot at a win, a case & a 1.76 planetary to replace it.


You feeling lucky today.................... well ARE ya' ??? =; =;



Nope Never been a lucky kinda guy lol.Gonna hold out,seems close freind has a 1.76 setup he willing to possibly give me when he digs -r -up. \:D/ ..
