Can I change a 3 speed transmission to a 4 speed transmission in a 1990 ford f150 lariat 2 wheel drive
I bought it with a 3 speed & I don't like the three speed tranny is going out so I thought if I could Id put in the 4 speed
you should just have to change the trans and the shifter.
Are you trying to go from an 3 speed automatic tranny to a 4 speed manual transmission? Or are both manual.
