Transmission weight

FORD GM Power Glide
C-6 173lbs TH400 181lbs
c-4 135lbs TH350 165lbs
AOD 700R4


All Transmissions were weight dry and with dipstick tube, converter and mounts . These transmissions where all stock and with stock converters.
I will be adding weights and more transmissions .
The above weights are mine the below weights are what I found on my search for more trans info


Ford -O-Matic 228lbs
FMX 160lbs
C4 110lbs
C6 140lbs
AOD 150lbs



Trans Bellhousing
Face to Trans
Mount Length Overall Length
From Bellhousing
To Tailshaft End
C4 20¼-inches 30½-inches
C6 22½-inches 33½-inches
AOD 22¼-inches 30¾-inches
E4OD 29 3/8-inches 37½-inches

Interesting data...... I'm assuming weight is with a stock convertor?

yes , I will keep this up dated and edit/change data as I keep checking to make sure that what I post is fact.

Can this be made a sticky so that everyone can find it easily for reference. I was surprised that the Turbo 400 and 350 weighed more than their Ford counterparts!

Notes:

- AOD and C4 weights are as measured by me using a standard bathroom scale.
- FMX and C6 torque converter weights provided by Steve Grossen (also used
bathroom scale).
- Ford-o-Matic weight is an assembly line weight provided by my Dad.
- C6 weight is from "Engine Swapping Tips and Techniques" which also lists
the C4 at 109 lbs.

Thats OK my C6 will stand numerous beatings isn't that right Mike.

These Numbers where with stock not hp transmissions taken 20 plus years ago.

I'd bet money a 6r80 trans has the least amount of parasitic drag in 1-1..............no bands or one way rollers ...

I would like to see what the parasitic drag of a full race prepped and rollerized c-6 is. My guess would be in full race trim and rollerized that all transmissions would become extremely close in parisitic loss.

I took out a C-6 and installed a Power Glide and the glide weighed 15 lbs less,
Glide was JW case with bell full roller with 9" conv. with a quart in conv.
, C6 was pulled fluid drained but 9" conv. was full

A stock case would weigh less but I didn't trust it behind a BBF

Great thread !
Good info.
I see there is 40 lbs diff. between a C-6 and C-4. Good to know.
