C9 auto replacing c4 in 302 xw

having problems with the c4 thats in the 302 xw at the moment, would a c9 go into the xw to replace the c4? is it the same bolt pattern and everything, flywheel etc? Its for a mate and I have no knowledge about these transmissions at all, please help.

There is a similar thread on another site at the moment. There is NO difference unless you are "south of the border" (a C9 is actually a type of caterpillar diesel engine).

There are two different styles of flexplates/convertors and boxes (windsor and clevo). If the bellhousing looks the same (exactly the same) it will fit no probs. Otherwise you need the flexplate and convertor to suit.

early c-4 24spline, later c-4 26 spline, theres pan fill boxes, case fill boxes, small convertor (c-96 c-98) large convertor c-10 style c-5 valvebody revisions etc. Plenty of different boxes, thats why in good old Vic they are called by their proper names for identification. Main types are case fill, pan fill, 26 spline, 24 spline, dual range v/bodys, single range v/bodies. Most 'guts' interchange throughout, my favourite is case fill c-9/8 style boxes as they have the late type 'guts' with 26sp, smaller convertor, easy fit in smaller tunnel app's and are strong, upgrade with a shift kit/manual v/body billet servo, hardened input shaft, 4 pinion planet and torrington bearing thrusts, there you have it. Small, tough as nails and a wee bit lighter than an FMX

So, basically a 6 cylinder C4...... (sorry, had to say it!!)

Fair enough, mostly 6 cyl xa-c taxi boxes were c-9/6 with the cast iron bell, was the case fill v8 box. But as the bw35 boxes were shitting themselves doing anything harder than normal citizen duties, a bloody heavy cast iron bell was made (to dampen the rocketship 6 cyl performance )to adapt it to the 6. C-9 = case fill small convertor.
