When I drive my car its slow to shift and also gets stuck shifting like it has no accelerarion. It never stalls on me though. Now some people saud it was the egr valve and a lot said it was the tcc trans solenoid. Idk what it is other than that the engine and tranny is fine and btw its a new transmission and the check engine light is on but qhen I use the scan tool it doeant give me a code just says pass. Any advice would be nice thanks.

Go to a place like autozone and have it scanned, then post up the code here. Otherwise we are just guessing.

Ok ill post it sometime today

if they dont come up with anything find a tranny shop that will scan it for free. youre looking for codes that start with 18 i think. im guessing 1811 (max shift adjust)

The code that came up is P1133

from what i can tell, its unrelated. thats just from searching the forums so i could be wrong.

i would take it to a tranny shop that can test it with a special transmission code reading tool they plug into the obd2. be careful where you go though, find someplace free.

thats how i found out what was wrong with mine. the zone couldnt find any codes.

Oh ok thanks for the info and what exactly was wrong with your transmission?

mine was doing alot like what you were talking about, not so much getting stuck between shifts as slipping. eg, the rpms skyrocket between gears. and then it would decide it was slipping and bump the pressure way up to where you would have teeth jarring shifts. i took it to a tranny shop by way of advice from someone either here or the buick forums and it was throwing code 1811 which is max shift adjust, which either means the shifting solenoid is gone (common problem in these trannys about $400 with labor) so i did that and that didnt fix it, which meant it was the clutches so i had to have it rebuilt for $2500.

heres the link to the buick forum thread i made.... looking back, it seems alot like your car.

Here'* what that code is, https://www.gmforum.com/obd-ii-trouble-shooting-153/p1133-284141/ Start with fixing that. Then see if the shifting problem is still there.

Thanks my story is a bit simular to yours, but i didn't spend that amount of money you spent and i just bought the buick a couple weeks ago. Weird thing is it'* a nerw transmission dunno why it would be doing this. The transmission has 60k miles on it. Danthurs what would be the part that i need? Would it be the HOS?
