My current project is a 32 Plymouth PB 3-window coupe powered by a Desoto 341ci Hemi coupled to a 727 transmission. Believe it or not, this hotrod project started with disassembly of a low mileage car in 1965 and has had four owners before me who have all contributed to the build but none ever made it to the street. The hemi engine was built in the 70's or 80's but had never been fired until I started it 10 days ago.
My current problem is that I'm unable to identify the 727 transmission and need to buy a high stall convertor for it to keep it from dying when shifted into gear. It has a fairly big Crane cam in it that doesn't have enough torque at idle to keep running in gear.
The numbers stamped on the transmission above the pan on the driver side are "J2801542 3899434". That doesn't match any of the seven pages of numbers in the list I found on line. Can anyone help identify this?

 

I didnt find the number as well....
But if its your average 727 ?? TCI Shows a 28 Spline converter that fits 1967-1981 727's...
Worst case... You would have to send your convertor in and have the stater changed out for the higher stall.
But im going to guess that its just going to be the average convertor... Maybe a phone call with some dimensions may help to a convertor company teck line.
Keep us posted... Good Luck
