Thanks for the information, the chassis is the same as a 62 c10 with torsion front end ect ect, I was given this ID chart and i have identified that mine is the 344 chevrolet transmission, i will rebuild this! i found out today that the second gear has a back cut on it that is to keep it in gear, and if that back cut is worn it would jump out like mine, so i will have to find out how many teeth this second gear has and find a replacement...

thanks
jeff
