4L85e Torque Converter info
 

2005 Suburban with 8.1L 496 bigblock with 4l85e, not an Allison. All stock, vehicle has never been touched.





Having a hard time finding information dealing with the stock converter, have looked at all sticky threads and other sites/databases and nothing is seeming to match.





The converter appears to be stock, having the factory GM hex style bolts holding it to the flex plate.


Converter has one sticker on it, has green and white "paint dots" with the numbers 2422-7939 on the sticker. (THIS HAS BEEN CHECKED TIME AND TIME AGAIN, it IS NOT 2242-7936, as that is the closest number that matches but is still incorrect)


Converter also has "K1-K628" stamped between blades on the outer casing.


Looks to be 13 1/2 inches in size and has a 18xsx-22xx stall (considerably higher than usual in HD applications).


Vehicle has never had the engine or transmission serviced (?).


Printed on the outer blades in ink is "THREAD" in all caps, followed by some numbers that are not legible.





Cannot find any part numbers, or application codes to match any of what is written. The closes thing to matching was a converter that ended in 7936, but did not match the description of this converter.


Any information would be appreciated as it seems that this thing doesn't exist.
