man these early 273' give everyone a headache sooner or later,
A little story to make you feel better and your entertainment as well.
7 years ago i purchase my 71 dodge challenger.
The transmission would always slip into 3rd gear.
One hot 100* i took the car for a drive and got stuck in bummber to bummer traffic,
I tooasted the Trans and it wouldn't gointo any gear.
Get the car towed home order myself a fresh 727 and a 2500 stall convertor that same day.
Next week end I get my transmission install the lines bolt up the transmission go to slide the convertor foward
Learned real fast about the early 273's that day
