I plan on doing some mods to my c-4 tranny this winter and have a few questions.
I'd like to install a manual valve body. Will I need to remove the tranny to do that and what are some goods kits.
Also, what servo is stock in the c-4? Will replacing the servo with a different one make a difference in performance in the tranny.
Can these mods be done by the average person?

the servo and vlave body can both be done in car just drop the pan,and the only thing a servo will realy do for you if give make the tranny hold tighter while in gear and you could probaly get the manual valve body from b&m,tci,and a couple of other place try these www.summitracing.com www.jegs.com

What do you mean by average person? If you are comfortable working on your car and patient with small parts assy, then you can install a shift kit. Just be careful, I almost lost a little bitty spring and ball. Do it in a very clean area...

you can do both with out taking the trans. out. I run the PA full manual reverse valve bodie in the wifes trans and I did a c-4 for a friend and I used the Dynamic valve bodie in his it was $40 dollars cheaper and if you take them apart they are the same things.also you should run a big front servo in that thing or you will be putting a front band in it soon that is one the key things with making a C-4 last.lots of people are selling them now or you can use the Ford H -servo it will have the letter H on the outside that is the best Ford servo I have seen the H -servo work well in 9sec street NOS car and work good in the wifes street car running low 11s in a full weight street car.for years at a time.with out front band problems.
