I bought a 1985 Mustang that has a 69 4V 351W and C-4 trans put in it. I am having a tough time with the C-4. It has a small B&M trans kit in it and was doing well until... I have now lost 2nd gear. It goes from 1st to 3rd???? Whats that all about? Any one have any ideas? I am thinking about pulling it out in favor Of a TCI built C-6.

I wouldnt put a c6 in it. Especially one from TCI. A c4 is the better trans. The only thing a c6 belongs in is a pickup truck.Just my 2 cents worth.

First of all Rene, two things.
1) As the computer geeks say, "garbage in, garbage out". Crap parts will break or wear out prematurely on anything. 
2)A well built C-4 will withstand anything you can throw at it. My cars, Steve W's and KV's alone are testaments to that. ------------------

Yep,C-4 trannys can take 500 plus h.p. and transfer more power to the ground than most autos. SteveW [This message has been edited by steve'66 (edited 12-21-2002).]

Oh, i dident mean any thing about C-4's.Im am quite sure that this one was never rebuilt or if it was god only knows who did it... This one just has a shady history( that i do not know). I have TCI C-6 that is ready to go in what ever its just Sitting on the floor. its my old drag trans back when a no one built a good C-4.. And i all ready have it.
On a difrent note : what would you recommend to go in to a C-4. I have heard all sorts of stuff. As you can easely see i am a stick kind of guy (i can rebuild those). Any one know of a contact down here in South Texas?

My race c4 originally came from Transking, and they are located in Galveston. But after having them flat out lie to me more than once, I personally cant recommend them to anybody now.

On the subject of trannys...My 75 Elite has the 351M and FMX, with 54,000 original miles on both. Arizona car right up until earlier this year, when it was brought to Pennsylvania. I got the car on eBay for $1500. Very clean, no rust, etc. The guy drove it up here from Philly for an additional $250...distance of about 277 miles.Anyway, I've found that the trans does not want to shift up out of second. Does that sound like a minor kickdown linkage adjustment needed, or is it likely to need a rebuild? If it needs a rebuild, would it be wiser/less expensive to get a different trans entirely? Would it be better to get another FMX, or change to a C4? I would like to have a good transmission, but not spend a bundle on it. Thanks. David

Take a look inside the servo housing on the
right side, make sure the two o-rings are in
good shape. If one or both have gone bad it
could affect the second gear.If you decide
to take a look inside, make sure to turn
the adjuster on the left side all the way
in before you remove the servo.This prevents
that the band comes loose when you
take the cover off. To ease installing the
cover ,use two long studs to pull
the cover against the housing,then install the short bolts.
All this must be done with the pan and
valve body removed to ensure the proper
position of the intermediate servo push
rod in the band.
Merry Christmas.

Since the band is good and you have the valvebody out,air test the servo.If that applies the band ok then you have a v.b prob.Depending on the model c4 you have,i had a greendot c4 that someone put a checkball where it shouldn't have been,lost 2nd.The ball was actually jammed in the hole in the sep plate that feeds 2nd gear..
