The simple question is, do the 6 cyl powerglides have a removeable bellhousing? None, some or all of them?

[wot179]

Yes. Some V8 ones too.

[Dr Terry]

Yes, all Holden 6-cyl Powerglides (HD-HT) have a separate bolt-on bell-housing.

 

HT 253/308 Powerglides also have this.

Thanks very much.

[yel327]

6cyl ones also have a trimatic/M15 3spd back end ie they use the same crossmember and speedo cable is on the RH side. The 253/308 examples use the 6cyl's case but have a V8 back end that use the same crossmember mount as a Saginaw.

Bomber you forgot 179 (and 186S), maybe 149 also although you may not have been able to get a HD with 149 auto.

[madtoranajzedded]

maybe we could put up more info on what the numbers stand for and what model they are out of.im pretty sure this is out of hk-ht-hg as was

sourced from Bellarine classic auto in geelong as thats all he has.there isnt many numbers on her

 

on ths side casing under powerglide has patented 57-59-60  made in canada

on the stator has F screwdriver stamp then 25 then  GM 5... in bottom pic looks like day and night.

these were in u.s postal van wernt they

What is the gear ratio in Holden 8v glide with the big output shaft? i pull one part yesterday to take the gearset but it looks like 1.82 with 27 output shaft

I think I could build one of these glide with my eye closed, not much inside and very basic.

[yel327]

Holden V8 Powerglide are the same as 6cyl. Only the bellhousing and the tail housing (with different speedo drive) differ. Rest is the same

[lakeside]

So they are all 1.82 gear sets in all Holdens. The output are different 16 vs 27 spline.

[yel327]

Not as far as I know, they are the same output shafts too, just like V8 trimatic vs 6cyl, V8 aussie 4spd v 6cyl. The only GMH passenger vehicles in that period with gearboxes with big outputs shafts are HQ 350 (Muncie and TH400) and HJ-HZ or VB with TH400. Some of the Powerglides in Holdens had a closer ratio set - those behind 307 in HK-HT, and 350 in HT-HG, but these were different boxes without the removable bellhousing. 

[lakeside]

Here are the 2 gear sets.










I have 2 glides, one is GM 1.76 in pieces with a broken carrier which is a 27 spline output. So I bought 308 glide which has the long extension housing, 27spline output which is the same extension housing as my GM glide 1.76 but has the small 1.82 carrier. Did GMH put 1.76 gears into small 1.82 carrier?

[madtoranajzedded]

Mine has the 1.76 gearset and front input shaft been heat treated to cope with 600hp .

Craig at craigs automatics said there isnt any
point beefing up other internals as tne imput shaft is the first to break.unless of course you have more hp

My memory isnt that good but she has an aftermarket forward clutch hub which is thicker
to take more clutch plates and i think he drilled a little hole in case to better apply the clutch
pack,also a needle roller bearing was used instead of the thrust washer has manual valve body and
transbrake.deep pan and a dual oring servo piston.that was needed for the transbrake .if it didnt have that and ring busts she would take off in reverse lol..stator face was machined etc.

Theres a little bit involved in it.i think
Cost was 2450 to rebuild + 200 gst.

I don't think that table is correct. There are no HG 253/308 with Powergide, and HT 253/308 Powerglide has the 1.82:1 gearset. The 253/308 Powerglide as I understand it is a 6cyl one with a specially made bellhousing, V8 pump and V8 tail-housing. I think the V8 tail-housing was used so the HK gear linkage would fit as the 6cyl one won't work with the V8 bellhousing as it goes across the front, the HK V8 one is at the rear. I'm also intrigued by the difference quoted between column and console shift - as far as i'm aware there is no difference. HT-HG Trimatic are different for column and console shift but not Powerglide? Unless the assembly comes with the gearshift linkage?
 

[lakeside]

Do the Holden 6cy & v8 have the same pumps stator tube? The Holden & GM glides have different stator tubes as well. I'm starting to think I bought a 6cyl Powerglide with a V8 housing.

The drum can be manhined on the inside to fit extra fiber and plate and clutch hub or aftermarket drums up 10 fibers.

I couldn't hand over $2200, you should pull one part and you will be surprised how basic they are.

Not sure which part that is, explain whee it is and i'll look in the HT parts book. The 6cyl and 253/308 boxes look pretty much the same apart from the bigger converter and where it goes into the box but lots of internal parts have different part numbers. Thy appear to essential break up into 4 x different boxes internally:

 

161-186

253/308

307

350

 

although some bits are common, eg the 253/308/307 share the same converter yet the input shafts are different, and the pumps are broken up as per the above 4 x types.

[lakeside]

The GM pump is the ground and it has a longer stator by 15-20mm tube than Holden glide.

Yes, that table is typical un-referenced Holdenpaedia guesswork.

 

AFAIK, factory workshop manuals & part catalogues both verify that all Holden 6 & V8 Powerglides got the 1.82 gearset, while 307/350 SBC V8s got the 1.76. 

 

On your point re: the difference between column & console shift 6 -cyl Powerglides, the lever is an integral (welded) part of the selector shaft going into the box. This means that an as assembly they will have different part numbers. This doesn't apply to the V8 boxes because their selector rod comes from behind regardless of shifter locatation.

 

Dr Terry

[yel327]

Ah, that explains the 6cyl box difference. A console shift 6cyl Powerglide would be relatively uncommon then.

[madtoranajzedded]

I bought this as a spare .would there be
anyway of knowing what gearset is in her
without dissasembling,

are they all made in canada

Whats the block thingy on outside of gear

Sorry for all the questions

I wonder if that is because the Holden V8 is 3/4" shorter at the back than a SBC? That part in the parts catalogues is in group 4.226, called COVER ASSEMBLY - with stator shaft. It is a different part number for all 4 x applications (6cyl, 253/308, 307 and 350).  All I can find using the part numbers in US literature is that the 307 one (3845823) is 1962-1968 all with powerglide except 327 and 409. And the 350 one (3950391) is for all V8 powerglide applications post 1970 and all 6cyl post 1970 with oil cooler bypass valve. The 6cyl Holden and 253/308 part numbers are not US numbers. The 253/308 number is a wierdo I've not seen before, 5258773, the 6cyl is a GMH number 7420938. The 5 prefixed part number must be from another GM division that used powerglides like Olds, Buick, Cadillac, even possibly another marque altogether like Jeep that used them. Some cars even had them as tranaxles like the Corvair.

It will be the 6cyl gearset, that is a HD-HG 6cyl box. You can tell by the RH exit speedo cable.
