flat towing a 727 torque flight W/O pulling the driveshaft

[OG max wedge]

i'm trying to find out how long or how far you can tow a car with a 727 auto trans with out pulling the driveshaft the car in question is a 1964 big block, the front of the car has some tow bar brackets and mounts that have been there since the 60's i know this car was taken to the drags and street races back in the day but i can't imagine the guy pulling the drive shaft everytime he took it out
my local aamco transmission says i can tow it 5 to 10 miles with out a problem... you do you think
any help would be great

I have a 62 dart use to flat tow it all over never pulled driveshaft .I heard before 66 the trans had two pumps in it.Front and rear that it stayed lubed so flat towing didn't hurt it.But i have towed mine over 25 miles each way.

True. Those early 727's had a rear pump as well. Problem is, if you tow one fast enough it will try to turn the motor over.


(yes, that means it could be push started)

even if the car is in Neutral ? what would you concider too fast? more the 55mph?

It shouldn't in Neutral , .....I have seen these car push started at 25 to 30 MPH, ...Get them rolling and put them in Drive.

Just like everyone says, but it would be helpful to know exactly what is being lubricated with only the rear pump working. Since you can push start it then obviously some clutch pack and/or band is engaging to turn the input shaft (in gear) but where else does the fluid go? I'd still keep it at 55 max and short trips until you find out for sure.

I bet he did pull it everytime. trannys arent cheap and i know people who change third members at the track. pulling the drive shaft is easier than changing from street tires to slicks. jmho

Why risk it?

Why risk it?

Personally, I wouldn't risk it either. :no:

It's easier to Break it than Fix it.

Here is the information as printed in the 1965 Chiltons Auto repair manual. The torqueflite 727 1965 and back can be towed at 30 MPH for no more than a short distance ( what ever you consider a short distance ) The car will start if flat towed at above 15 MPH when put in low gear. The bottom line is you can pull start a 1965 or older torqueflite when pulled at above 15 MPH with the key on and the car put in low at abpve 15 MPH. Flat towing they say not very far at speeds up to 30 MPH or as you say pull the driveshaft. I would not flat tow them, We did not pull them then in the 60s because Dodge said not to.

Well, I did raise the question, and with this good info presented here I will have to side with the low risk crowd. It seems as though there is not a lot of lubrication done by the rear pump when the engine isn't running.

Should have finished my thought........

I would drop the driveshaft

Not to state the obvious, but if the car was being flat towed to the races, it runs...
Couldn't you just run the engine at idle and put the tranny in neutral?:shruggy:

dont see why not but a lot of race cars will load up and foul plugs if left idling.
