3-spd transmission original?
The previous owner of my 1966 Impala just stopped by today and dropped off the transmission that was "in the car when he bought it" (that was over 20 years ago). I was hoping for some help to see if maybe it was the original transmission.
The car: European 1966 Impala, 4.1L, 3-spd. "Made in Antwerp"
The transmission in question:
On the left side of the transmission case, near the shift arm I see the numbers "GM 4 3858992"
Under that is "K245"
I took the "3858992" to be a casting number but didn't know much else about it. I also looked on "oldride.com" and couldn't really tell if the "K" number was the number I was looking for. If it is, then I have a McKinnon 3-spd, made in February, and that would make the 45 the "day" but I don't think February has 45 days... maybe 45th day of the year?
On the right side of the case, there is a D and an N, with an arrow pointing to the "D". I assumed that to mean that it was made on "Day" shift.
Under that is "GM2"
Under that is "3858986"
Under which is "M8 5"
I hope I wrote this so people could follow. If needed I could always take pictures (after all, a picture is worth how many words?) but any help would be greatly appreciated.
