Hi all: I've got a 51 and the trans is supposed to be original (yea right). The numbers on the case are con5 beside that is 11D23 under that is GM under that is 591958. on the top cover is 591568. Can someone tell me anything about it. also where can I get a rebuild kit? thanks Rick
Internet Rick Send us a picture , that would help. What kind tranny is in your truck ? You can find all information on the internet ; GM Transmission identification sites are many. Rebuild kits are easy to get to on EBAY ! Depends what you need to rebuild offcourse ? Martinius.
Tranny Fun You didn't say if this is a side loader three speed (Saginaw) or top loader four speed compound low ('Granny Gear') Muncie tranny . In either case the " 11D23 " can be decoded to tell you the year & month it mas made , IIRC , " CON5 " simply means Assembly Line (conveyor) # 5 . Posting pix helps greatly , all of these old GM trannies are sturdy , well made units that are simple to overhaul or rebuild . DO be sure to clean the gears well & inspect for tiny hairline cracks ! very common and lead to exploding tranny when you least expect it . At the very least you can hang the gears from a coat hanger & tap them with a wrench , if not cracked , they'll ring like a bell , if cracked they'll make a ' thud ' sort of sound when tapped .
Oh , Yeah ~ The beat to crap sliding first gear with the straight cut teeth that are all ripped to shreds on one side ? it's designed to be flipped over and re used again , won't be silent but WILL be good to go for another 50 years....
Hi All It's a 4 speed. Someday I'll figure out how to post pics,or get a grandson to show me how. Rick
