Will a 1989 ford probe transmission out of the 4cly fit 1990 v6 both being 5 speed?
No, a 1989 Ford Probe 4-cylinder 5-speed transmission will not fit a 1990 Ford Probe V6 5-speed. Even though both are 5-speeds, the bellhousing (the part that connects the transmission to the engine) and the overall gear ratios are different and incompatible. The V6 engine is significantly larger and produces more torque, requiring a much stronger transmission.
