I need some help!?!?! Has anybody experienced rough shifting after they removed and cleaned their throttle body and a little bit of the inside of the intake manifold, or is it just me??... When its cold its very rough, but i can understand that... after its warm its still alot more rough then it used to be before i cleaned it. Do you guys think i did something wrong or maybe i forgot to connect something back in? Did i break my car??

I forgot to mention that i cleaned it with Sea-Foam, if that makes a difference...

I've heard some pretty scary experiences from others who used the Seafoam application, pointing out to things like mis-shifting of the transmission, engine not starting up normally, etc. Hate to say this but it sounds like you're one of the victims of the Seafoam trap...

Considering the enigne has nothing to do with the transmission lmao!


If your description of the problem is accurate in that the transmission now shifts harshly.
And you rememoved the throttle body.


You've most likely changed the adjustment of the kick-down cable. Which is what varrys the pressure in the valve body, which controls the force, speed, and to a more minor degree, the timing of the shifting.

did u disconnect the battery?

if so its going to take a week or so to re-learn ur driving patterns and smooth down a bit.

So what am i in for if im one of the people who get the trap for using sea-foam??

pure drifter= no i did not remove the battery, i didnt think it would make a difference if my car was shut off when i removed all of the connectores and valves..?

sounds like pheonix knows what hes talking about, is there anyway you can try explaining that to a guy who has no idea what your talking about, sorry to sound like a n00b... THANKS GUYS!!

the only thing i know about cleaning out the throttle body is that one bank of plugs will become black from the throttle body cleaner. i usually clean it once i am ready to replace the plugs. but i don't know how that would affect your shifting

hmm, so what your saying is that im still stuck at square zero then because that would have nothing to do with my problem then, is that right? Or am i just not understanding you?
