tranny I.D.

Where can decode the number plate on the transmission?
Thanx

Look on the driver's door or door frame, there is a white sticker with the vin, GVW, and other data on it, at the bottom of the sticker there are two lines of letters/numbers, look for what is below the "TR" on the second line from the bottom. Along with the year, we can figure out what trans.

Also, auto or manual, and engine size would do it otherwise.

77 F-150 4x4 351M 4 spd.

Sticker/plate missing from door/frame.

Oh. That's a little older than I am familiar with.
