Its an 89 f350 with 5.8, trans code on sticker says K. Which transmission is this? Finding stuff that says of but doesn't seem like it has it. Also seen where there is a switch on the dash for OD but mine doesn't have it. Which trans do I have? Anyone know. Seems like its a 3 speed only doing 55 mph. Any help would be greatly appreciated!!!!!!

 

I just read where it says its a c6 3 speed. The dash shows P-R-N-2-1

 

Transmission Code K is a 3-speed C6 automatic

 

Thank that's what I was looking for!

 

Ok looking to do a munual swap later but tryingto see is there a 6 speed that bolt to a 351 or will I have to go with a 5 speed? I know they made them for the 460 but not sure if that will bolt to my 351. Thanks

 

Six speed auto or manual trans. was never available w/7.5L 460CI engine. Even if there was one available it would not fit your 5.8L engine. Completely different bellhousing bolt patterns.

 

Ok must have heard wrong sorry, was there ever on made for 351 or just 5 speed
