Re: c4 identification troubles

So a C4 is a C4 is a C4 isn't necessarily the case?



My problem is this...



I have a '65 six cylinder coupe that does not have the original engine, it currently has a '67 six cylinder but I believe the C4 tranny was from the original '65. Now the tranny is slipping. I got a C4 tranny but my mechanic says it won't bolt up to the '67 engine. I figured it was just the bellhousings - this new tranny was in a V8.



Any help would be appreciated - what I need to look at to line up the engine I have with



And anyone in southern Ontario or upstate NY have a good C4 tranny for sale? And can guarantee it will bold onto a '67 6 cylinder?



Thanks.



Andrew

You need to be sure that both are from a floor shift car if that is what you have now. other wise you will have to change the shift lever. KB

Hi Tom, Kevin,

Thanks for your input.

I went to the shop today - the tranny that was in my stang is a 5-bolt. But this engine is from a '67 Mustang.

My mechanic says I should only look for a C4 for an inline six, and not get one that was in a V8.

Damn, had a line on a C4 but it is from an early 70s Ford with a 302.

Anyone in southern Ontario got what I need? I'm fast running out of good Canadian weather in which to drive!

Thanks.

Andrew

Get the one from the V8. it will work fine. and be stronger too. KB
