Suncoast Question

[Diddy]

While in T/H my 2/3 shift is pretty harsh. I have my ATS on Defuel but it does not shift like this in the other gears. It's smooth as butter, just 2/3. I have reset my trans several times but this is always the case. Does it need to be adjusted some other way?? Also, I never really noticed this before but when in OD and I shift down, it shifts into 3rd and then an instant quick shift to 4th and then OD. Is this normal?? Sorry for the Newby question.

Sled Puller,

Do you mean that the 2/3 shift is harsh on yours as well or that the shifting from O/D to 3rd was normal?

Thanks.

Thats not normal. I had weird shifts like that before and i had a broken solenoid spring in the VB. I got it fixed at ATS and now its smooth as ice.

NWT,

Which shifts are you refering to?? My warranty is coming up and I want to make sure that I am taken care of. What causes that spring to go bad?

never heard of a harsh 2/3 shift. usually it's the 3/4 shift.

Mine would hit kinda hard from 1-2shift and really hard from 3-4 shift. Then it would downshift really hard too. I couldnt even use T/H cause it felt like i was gonna leave my trans on the highway.

ATS said i had a broken spring in the VB and a hole that was drilled for the Transgo shift kit was too big. I had the whole VB replaced with a ATS and now its good. Those guys put a new filter, fluid, VB and had my truck for 6 hours........didnt charge me a penny.

Im not sure what caused the spring to break? Im pretty hard on my Trans tho so it wasnt a big surprise.

Originally I thought it was from defueling. So the shift sequence in T/H goes like this.....1/2 flares at times, 2/3 quick hard shift (almost chirps the tires) 3/4 smooth and 4/5 smooth. All downshifts are very nice. Now that I think of it, I usually roll my foot into it between the 2/3 shifts and then start letting off on the 3/4. I do this to get my load moving and up to speed. Do you think the higher RPM's are making me feel this way? Did I just answer my own question or can this be adjusted by a Tech 2 or something similar or am I way off and could need some new parts??

If its a violent shift i would be 99% shure thers something not right inside your trans. Mine only shifts hard when T/H and Co-pilot are cranked up and im at WOT. Other than that it feels stock.
