Black,
Even if done correctly, and planned ahead, rebuilding a tranny on a syclone can be a nightmare, i took my trany to a shop that everyone in town recommended, he had built many 10 second and udner cars that run at the track and had a great reputation, so i thought i had nothing to fear, well, i was wrong, he assumed the sy/ty 700r4, and commense my story: the forst time he rebuilt it and gave it back to me, it was shifting like crap, i couldnt believe how mushy it was, he kenw i used the truck for racing and said he was going to make the shifts chirp all 4 tires, well, needless to say the next day the tranny failed because of low fluid pressure, he payed for the tow back to his shop and tried to rebuild it agian, this time he blocked the actuators off, used some huge valves and put it back together, we,, it still shifted like complete ass, he said he wanted to keep it overnight so it wouldnt burn up agian, well, the next day he ulled it out AGIAN and rebuilt it infrfont of me, he said he was so pissed off at my syclone that he wasnt gonna F$ck around with it this time, he said it was gonan chirp all 4 tires and break my neck this time or hed give me a full refund and build it for free, well he went back in and did all sorts of crazy sh&t, called hi buddy from california that had some experience with sy/tys and found out he was using a "standard" 700r4 valve body that was blocking a pressure hole thats supposidlky only standard on a sy/ty, and it was cuasing it to shift like crap, wel after he put the right vavle body in it was shifting like a god damn demon of a syclone, i loved it, the moral of this long and drawn out and most liely mis-spelled story is, Make sure whever rebuilds it knows what a syclone is, and knows the differences between a sy/ty and a regular 700r4 tranny, because there is alot of stuff thats differnet, GET AHOLD of the tranny guru brian hartman he will steer you in the right direction, he is the god of all things tranny on a syclone/phoon, he even offered to talk to the guy that was building my tranny and try to find out what was wrong but it was alrdy fixed by then, if you are going to get a torque converter get the hartman 9/11, if you want a fail safe tranny that will 100% shift like it should, get a hartman tranny, but whatever you do, dont stick yourself with a rag tag tranny shop thats thinks a syclone tranny is like every other 700r4 on the planet, because its not, another option is the GM replacement its around 1000 dollars i believe, and whatever you do, dont let the same mechanic that ruined your tranny by taking the tv cable out try to fix it, infact, stay as far away frrom that dude as you can, and get ahold of hartman, peace
