Is the Borg Warner 5-speed in the XE Falcon (not the later T5) a direct swap for the 3-speed? Is it a development of the 4-speed (in some models the ratios are the same)?
I have a non-Ford vehicle that has the Borg Warner 3-speed with a floor change. The 4-speed can also be fitted (it was used in a different model with the same engine). I've been told the 4-speed has an extra bolt hole in the bellhousing over the 3-speed - does the 5-speed use the 4-speed's bellhousing?
Are the 3-speed, 4-speed, and 5-speed the same length? Or are they all different requiring different driveshafts?
I know Ford use a 10-spline input shaft, where other manufacturers used a 23-spline input shaft (3-speed and 4-speed), so I'll have to use the Ford clutch, but that shouldn't be a problem.
Is the shifter in the same position on the 5-speed as the 4-speed?
all 3-speeds except the Charger had the same ratios 2.95/1.69/1.00
XA 4-speed same ratios as Leyland P76 2.78/1.93/1.36/1.00
XB 4-speed same ratios as Charger 2.82/1.84/1.32/100
XE 3.3 4-speed 3.24/1.96/1.26/1.00 5-speed 3.24/1.96/1.26/1.00/0.79
Does the 5-speed share the 4-speed's internals for the first 4 ratios? If so, can the early XA/XB close ratio gears be fitted into a 5-speed?
