i recently swapped my 3speed for a c4 auto out of a 73 bronco which i have for parts. i have had nothing but headaches!!!! i have pulled it out 3 times for problems. has anyone built one for heavy duty use i.e. severe mud,hill climbing?
the c4 shifts and runs fine until it gets hot apprx. 20miles and then trans fluid pours from behind the flywheel. i have replaced the seals and bushings. no luck. it is driving me crazy. any help would be greatly appr.
NO I DID NOT INSTALL A COOLER. JUST STRAIGHT TO THE RADIATOR WHICH IS NEW. I DID NOT KNOW IF ONE WAS REQUIRED. DID THE ORIGINAL'S HAVE COOLERS? THE 73 I TOOK IT OUT OF,HAD THE MOTOR AND RADIATOR PULLED OUT OF IT WHEN I BOUGHT IT FOR PARTS. COULD THIS BE MY WHOLE PROBLEM? ANY SUGGESGTIONS FOR AT COOLERS. IT IS KILLING ME HAVING MY BRONCO SITTING IN MY DRIVEWAY WITH THE SPRING WEATHER HERE IN MISS.,AND I HATE TO HAVE A REBUILD UNLESS I NEED IT FOR SURE. THANK YOU FOR ANY HELP.
IT IS LEAKING FROM BEHIND THE FLYWHEEL AND POURING STRAIGHT DOWN. I REPLACED THE FRONT SEAL AND BUSHING. STILL THE SAME. IT WILL IDOL ALL DAY LONG AND NOT LEAK,GO DOWN THE ROAD A FEW MILES AND IT BEGINS POURING. AS SOON AS YOU SHUT THE MOTOR OFF IT QUITS. SOMEONE TOLD ME TO CHECK THE VENT TUBE. I THINK I FOUND IT BY HAND,DOES IT HAVE A METAL CAP ON IT? IF SO IT MOVES FREELY UP AND DOWN SO IT DOES NOT APPEAR TO BE STOPPED UP. I AM TRYING TO FIX IT WITHOUT PULLING IT OUT BUT MY OPTIONS ARE RUNNING OUT. THANK YOU FOR ANY HELP. I DOUBLED CHECK MY RADIATOR COOLER TO MAKE SURE IT WASNT STOPPED UP AND IT IS WORKING FINE. THANK YOU FOR ANY HELP
The vent is in the adaptor between the transmission and transfer case.
How does the torque converter look? Was it from your parts truck or did you purchase a new one. It is possible to have a crack in it that will not leak at idle. When you drive it, the transmission fluid pressure builds, causing it to leak. It could also be coming from the front pump itself where it seals to the transmission housing.
Either way, it is going to take pulling the transmission out. You might think about having it built and getting a new converter. To answer your original question, the C4 can be built to handle lots of power and HD use. You just need to focus on what your main use is going to be.
