soooooo, is a c4 suposed to last more than 60 miles? (no kidding, 60 miles) cuz i just filled mine with metal dust and burned up the clutches. hmmmm, might just return that one to the transmission shop. p.s. the car has never been over 2500 rpm. i was just breaking everything in. guess she is broke in now!
Bummer man. Sounds like a warranty job to me. Hope you dont hear the "No warranty on Performance build" line of bull crap. something definitely went wrong there and out of your control.
wow. as long as it was installed correctly with the shiftier properly adjusted and the kick down lever hooked up you should have no problem having it warranted
maybe...I had (2) that didn't get out of the shop... (1) about 2 miles...several, less than 100 miles... if PaulS is feeling better he may come on and tell you how great C4s are...
Kickdown linkage doesn't make a difference. I have run all of mine without kickdown for the past 6 or 7 years. Still running strong. But they leak...
60 miles ? Gee that's pretty good. I had one that didn't make 10 miles before puking. Were the bands properly adjusted ? How did you set up the shifter adjustment ?
C4s can last 20 years or more. If you had it rebuilt then return to the shop on warranty. If they won't cover it then call the BBB and your local Attorney General. If you can afford it and you can't get it redone locally the Broader Perfomance can supply one at a reasonable cost - they even have one rated at 500hp for only $900. Call Jay before Noon Central time and talk to him about it. Tell him that Paul, from Seattle told you about him on the forums. If you can't aford that then buy a video from Bad Shoe productions and rebuild it yourself.
i believe that the kick down lever controls line pressure and when you dont run it, the line pressure will never rise enough to hold some good power. but as people above have stated, it shouldnt allow the trans to die in 80 miles
The "Kick-down" linkage regulates governor pressure and modulator pressure and above 50 MPH it raises modulator pressure that affects clutch apply pressure. Although it doesn't control line pressure the effect is virtually the same. Without it connected the pressure in third won't rise with loads where the vacuum is 10" Hg or less. Pressure in third will remain near 90 PSI. With it connected the pressure will rise to as much as 175 psi with stock springs at full throttle. You can't feel the difference but under high loads the direct cluches can slip and burn. I have rebuilt many C4s that show the effects of running without the "Kick-down" linkage connected. It does take a few years to show but by then - too late. Some guys get away witout it by manually shifting and keeping the C4 in lower gears when loads are applied. They still hurt their transmissions when doing full throttle passes on the two lanes - and never know it until it fails.
