ill just lead with, i am probably into the needing a th400 territory at this point, but finding one around here with a matching transfer case and a reasonable price just doesnt seem to happen, which is why i ended up with the th350/205 combo the begin with
so, background, truck has a 383 with dart iron eagle heads, 10.4:1, erson retro fit roller cam 286/294 .548/.548 lift, 750cfm quick fuel carb
the trans has a full TCI transmission kit, with a hardened outer race for the sprag, ATI input shaft(twisted the stock one off)hughes 2500 stall converter, very firm shift kit
truck has 4.56's 33' tires and weighs in at 6200 lbs
was driving to the gym saturday, was shifting really weird, would do ok in 1st and 3rd, felt like 2 is slipping, i can manually shift through the gears, 2 slips to 4-5000 rpms, lift and it will shift into 3rd, nothing wrong with 3rd.
leaving the gym i payed more attention, it s pretty much shifting from 1-3, rpms build real high in 1, then it dogs a bit into 3rd, checked the fluid, fluid is a nice bright red(royal purple) small amount of black "powder" on the stick, which makes me think the clutches arent the issue, ive read alot about the intermediate sprag shattering,
havent torn it down yet, i need it to move on its own for a little longer....looking at the 36 element drump upgrade from tci auto, anyone use one? any other suggested hard parts i should put in it while its apart?
just thought id see what you guys thought
