I had two ford trucks with SLUSH BOXES , The 73 F 250 4X4 that got UP GRADED two weeks after i bought it and the sun kissed Lemon 1978 F 250 4X4 that never made it home the first night i bought it and had to be towed back and would not last more then 9 days with out a tow back to the dealer . The 73 was a gutless pig and had a bad drinking problem . The 360 got pulled out and a 428 S/CJ dropped in that solved the gutlessness and also the drinking problem , the C 6 got major shell we say UPDATES on the bench and lasted five years with no problems , BUT back then ya had something to work with . The 78 the C6 in it was garbage straight out of the factory and when built at the factory one clutch disc and one plate was never installed in the forward clutch pac. and the stupid mechanic at the dealer never checked and just put the same amount in each time it failed , he did this four times in six weeks , Then they istalled a NEW from the factory complete trans and it lasted four days . Not till i pulled that one myself and scattered it all over my bench did i find the problem . Ford made major cost cutting and changes to the OLD C 6 way back in 10 May 1975 when they no longer used the 6 clutches and 6 disc in ALL three clutch pac. and went to four four and three softened up the shifts lowered Pressures and shift points. . Now never being in and EOD they are somewhat like a C 6 with a OD unit added and now electric shift and computer controlled shifting . They now slide the clutch pac's in and out to the point ya hardly feel a shift and they added inside the T/C a lock up clutch that usually loc's up around 35-40 MPH to help with fuel mileage and act somewhat like a std. trans in the higher ranges . But if the lock up pressures are low to start with and ya have enough pony power to walk thru the lock up then ya shorten the life of the lock up clutch . Myself i work b the old school thought and that is IF you want to haul IRON then it takes IRON to haul it with in other words get a standard transmission . Replacing a OLD fashion Clutch is a LOT easier and CHEAPER then a slush box rebuild . Even the might Allisons FAIL , Cat Power shift FAIL . OLD STUFF is almost eternal . Yes i have had OLD clutches fail The clutches back in the late sixty's were failing due to eye bolt breakage , had one fail at 7500 RPM , NOT FUN . pulled the centers out of three , Due to a few more Pony's then it could take . But all took less time and money to replace and or repair. The only Slush box that was a fast easy and not to expensive to do were the old 727 and 904 torqueflites . OUT and back in with a full rebuild in usually 6 hours with two working on one that knew what they were doing in under 3 1/2 hours .
