Van 727 transmission

[Cythomas]

Will a van 727 transmission work in my 1973 Duster? Do I need to change anything?

Thanks

If the tail shaft is the "normal car length" tail shaft, should be pretty basic. I have a car 727 in one of my vans so... But be aware some are lock-up and such

Agree and i have used van trannys in my Dusters the only difference i found was the dip stick and tube are shorter in the van and are a little harder to reach in a car .

I put a 79 van 727 with a 318 in a 70 Dart 340 that had a 727 previously, and nothing had to be changed.

As long as your Duster isn't a console automatic car, the van 727 will work just fine. The truck/van 727 tailshaft housings do not have the tabs on the bottom to bolt the shift linkage to. Also, the truck/van tailshaft housings have the snap ring peep hole in the side of the housing instead of the bottom of the housing like the car housings.

Reprinted from allpar
"A-727 transmissions from their inception until 1966 have 19 splines on the input shaft. Non-lockup 727 transmissions from 1967 onward have 24 splines. Lockup 727 transmissions that debuted in 1978 had 23 splines.
Not all 727 transmissions made after 1978 were lockup; specifically towing package 727 transmissions commonly were non-lockup, and would have the '67-onward 24 spline input shaft. The A-518 overdrive also has 23 splines. The output shaft has 29 splines.
A-904 transmissions from their inception until 1967 have 18 splines in the input shaft. Non-lockup transmissions from 1968 have 27 splines.
Lockup 904 transmissions appeared in 1978, and have 26 splines. A-500 overdrive transmissions also have 26 splines. The output shaft has 25 splines.
If in doubt count the number of splines."

I had one of those tailshafts with the snap ring peep hole on the side and it hit my trans cross member in my 68 A-body.

Kept knocking out motor mounts and trans mounts until I figured it out and swapped the extension housing.

Good info! The only car I ever put one in was a 71 Challenger that was a column shift automatic. I do remember it being close, but had maybe an 1/8 inch gap. I guess the upper hoop part of an E body T bar crossmember must be bigger.

My 70 Dart Swinger 340 I put it in was a console with a floor shift and everything worked out with no changes.
