Built tranny guys help??
on my HTS build tranny, since i've had it done, for some reason, when iam in the throttle more then 1/4 pedal, and especially goin up an incline, it will shift into 4th fast, and when the TC locks up, the whole truck jerks bad, turbo barks, and all. i mean it feels awful. i no something aint right. i called Dusty at HTS and told him, he send me some VB parts, but that didnt do a thing. i mean iam even afraid to give it alot of pedal gettin on the interstate, cause thats when it does it bad. where there's the least little incline.... anyone got any ideas??? thanks

well i have the same trans you do. mine has never done it. you need to keep talking with dusty about it. if you let other ppl tell you how to fix it and mess it up I dont think they are gonna be happy about that. mine had a 50k mile warranty so I dont know why yours wouldnt either.

The explaination I was given is that the piston in the accumulator is weak. Dave hooked me up with a sweet Billet Piston, new springs and a block off plug for one of the channels. Mine would do what you described or it would do a serious BUMP BUMP 4-od shift which would cause horrible barking....

CTDowerTN TC locks up, the whole truck jerks bad I can see that just a good TQ Does it shift fast in to 4th? Or does it get to about 2k before it shifts each time? I know mine shifts real hard when you are lite on the peddle.TQ locks up hard to. But if i drive it a little harder it ok but the TQ still hits hard. I would like to know more.just trying to help!

how many miles do you have on the Tranny?
well i will tell you this my tranny did the same thing going into OD but i learned to drive around it. i have since installed a lockup controller so now i can bark the turbo at about 30 mph because thats when the TC locks up. the reason it jerks and barks the turbo is because the TC is locked up. it jerks because it transfers a large amount of tq that was being lost in the fluid coupling (TC not in lock up). the way to fix this is to change out the accumulator piston and spring to reduce the pressure going to the TC. this means that the TC will have more of a chance of slipping due to less pressure on the clutches.
dusty is a great person to talk to and to deal with i would keep sending you questions his way and work things out with him. i would think adding someone else's part into dusty's built tranny might cause warranty issues.

the thing that gets me is it does it worse when on a hill or incline, now if iam on flat ground, and get into the throttle about 3/4. it will shift into 4th fast, and jerk kinda bad on TC lock-up.....

if your tranny and converter are newer give it some time when i first finished my trans it would lock up HARD and after awhile it loosened up and all is good. it is doing it worse going up a hill because you are stalling the converter more and you are getting more of a rpm drop when it locks due to this causing it to jerk harder.
