67ssmike Jan 21st, 04, 7:05 PM can anyone ID this trans for me I know it's a borg warner but don't know to much else about it ..thanks :D case number 1304065903 w.g.div fp01 number in behind reverse lever 1304066901 David Bates Jan 22nd, 04, 6:19 AM The 1304065903 is the number for an aluminum case Super T-10 which was an OEM GM transmission used from 1975 through the early 80's. They were all 26-spline input and 32-spline outputs. There should be some circular grooves on the input shaft which will tell you what gearset is in it. Also, there should be some stamped letters/numbers on a pad right next to the side cover which will tell you when it was assembled. There is also a boss just above the side cover which may or may not have a partial VIN stamped into it. 67ssmike Jan 22nd, 04, 6:18 PM thanks for your reply.I went ahead and bought the tranny and looked it over real good heres what i found. 6-12-75 16s410435 wk952 number on the side cover 3-04-097-901 another number 8-03-75 3 rings on the input shaft i marked the input and output shaft and turned the input 2 full turns and that left the output 8 teeth short of a full turn.. would that tell you and gear info? also is this transmission strong enough behind a 425 hp big block ..thanks i hope this is good info i'm giving you as i'm not to hip on trannys.. :D David Bates Jan 23rd, 04, 6:28 AM 6-12-75: June 12, 1975 main case casting date 16s410435: 1=Chevrolet, 6=1976, S=St. Louis (Corvette), 410435 VIN sequence number, 1976 started with 400001. WK952: W=Warner Gear Division, K=November, 9=9th day of month, 5=1975, 2=2nd shift 3 rings on input: 2.64: 1st, 1.75:1 2nd, 1.34:1 3rd, and 1:1 4th. Referred to as the "W" ratio. 67ssmike Jan 23rd, 04, 6:54 PM how will that tranny gear ratio work with my rear gear of a 4-10. should i think about changing the rear gear.. being that this transmission came out of a vette I would assume it would be a pretty strong unit ...thanks for all the help ;) 67ssmike Jan 24th, 04, 1:20 PM I guess i'm just not in the click i ask questions and nothing gets answers.except you david thanks for your help.i'll just try another site maybe things will improve for me .thanks for all the help in the past graemlins/sad.gif elcamino Jan 24th, 04, 5:20 PM Originally posted by 67ssmike: how will that tranny gear ratio work with my rear gear of a 4-10. should i think about changing the rear gear.. being that this transmission came out of a vette I would assume it would be a pretty strong unit ...thanks for all the help ;) You are in the wrong area for any answer to that question. Most of those crusing here know hwo to decode things but the Transmission section will probably find more trans experts. David Bates Jan 27th, 04, 6:11 AM 4.10's would be a bit much. 3.31 or 3.55 would be much better and you'd be happier at highway speeds. Marcelino Jun 4th, 10, 10:13 PM My friend has a transmission and we want to now if it could be a m-22 or if you can help by identifying what type it is. It has a lot of number and letters like on one side... 1304065903 W.G.div FpG3 behind the lever 13-04-066-906 -Thank you Ethan1 Jun 4th, 10, 10:32 PM My friend has a transmission and we want to now if it could be a m-22 or if you can help by identifying what type it is.
