Suncoast should have been your first call instead of posting this all over the net. Just what kind of diagnosis do you expect from anyone that has no idea what Suncoast does in their trans? You have a warranty; use it.
Is it flaring any other shifts? Can you log it for us? Log the TCM and grab input speed, turbine speed, and output speed, also grab throttle and TCC state.
Is it worse in T/H or in normal mode, light throttle or heavy?

I really dont feel like not being able to drive my truck for another month and a half since it takes 3-4 weeks just to get it from canada down to suncoast. If you dont have any useful information dont post. :violent:
I have a buddy that is on this forum that is having the same problem. He has had his trans in a few months now and his 3-4 still slams hard. He has tried everything and can't fix it. He has been told by numerous people that the hard shift is the way it is supposed to be. I just had my trans built and mine was slamming the 3-4 hard to begin with. Have put about 400 miles on it and it calmed right down. Not sure what to tell you. Contact Suncoast and have it fixed up.
The transgo kit causes the 3-4 hard shift.. and yes it will calm down after a while.
This is different.. He says it's flaring the 3-4 shift.
Yes it is, light-medium throttle it shifts fine, WOT it will hang for 3-5 secs like its in neutral then slam into 4th gear, all the other gears are fine during WOT tho, then i dono about the reverse clunks. I cannot log anything right now i am away at work for 2 weeks, T/H is a little better but it still does it.
man reading threads like this really make me glad i went where i did.
have you tried resetting the taps more then once? maybe loading a different tcm os just for giggles? course im no expert but just an idea.
