Fox Body 5 speed to C4 convert.
 

I'm changing over my 89 Mustang from a 5 speed to C4 . I have a problem with the rear trany mount, It's a little to short to meet the cross member. Do I need a auto trans rear mount ? Help
thanks

same cross member I think. to make it fit cut the welds on the mount sleeves so it slides and elongate the bolt holes. once you bolt it up just tack weld the sleeves.

Or Ford Racing part# M-5059-A is an adjustable one. Will solve your problem. Check driveshaft length you might be short- Steeda makes a very nice billet spacer that works great.

Thank you Bob, that worked like a charm. And Glen I thank you for your input allso , I was tipped off about the spacer and was ready.
Now I just need to get the shifter instulled and cluch cable and speed-o cable out, some wireing and we can get it to the track.
You can allways count on Class Racer people
Thanks

We can sell you what you need. We stock the correct switch.

Thanks for the reply Capri, but I used the clutch interlock wires. Just hard to get the wires out from under the dash with the rollbar there.
It's done and running, now having a problem with a flare going into 3rd. the trans builder says it's a qt. low on fluid. We will see.
Thanks for you for the help

Flair or Flash going into third is common, depending on who built the C-4. We switched from a C-4 to T-5 because of the flash because we felt the stick was quicker and more consistant. We got over 2800 runs with a stock T-5. We now have a used TKO in the car with 800 + runs.

The flair seems to go away after the trans is warmed, or at higher RPMs
I also found the pan bolts loose. I don't think that has any thing to do with it. I'm going to put the qt. of fluid in it and try it. I have to put the exhaust back on to try it on the street.

Cool. That works too. We stock the correct NSS to convert to a C-4.

The flare on the 2-3 is an issue in the clutch pack as I recall. If its not more than 200 rpm, it will work fine forever at 6500RPM. An extra qt may not help. I believe I have 7qts in mine with a deep pan.
