How do I know what type of manual tranny I have in my 91' F-150 4.9l 2wd truck? I do know it's 5 speed, and what is the
"Bulldog Transmission" on a Ford.
I'm illiterate when it comes to transmissions. Thanks and I hope my questions aren't dumb ones.

 

You have a Mazda-built M5OD-R2.

"Bulldog" is a term used for a "granny" low creeper gear. Yours does not have that.
