ok so i have a 1989 dodge Dakota v6 sport 4 speed with O/D that i bought off some farmer for $380
here are the problems

1) transmission will shift into 1st then 2nd but not into third and it will go into high rpm's
2)when it has O/D on it will make a clunk and whine.. but not when its turned off
3) i put it on jack stands ... and shifted it into neutral.. and its slightly gives wheel spin
4) when i put it into reverse it will buck....
