mikebontoft doesn't surprise me one bit. New parts, even OEM for the past year have been junk. In fact, a few months ago I had a seized compressor new in the box.

GreySkorpion Yes, thanks for the update, proof even brand new parts can be faulty!

sailor Hooray!

Tx for posting the update, knowing the outcome could help someone else PLUS earlier posters aren't left wondering what happened.

Bad new part can make you run in circles B4 figuring it out, and having to dive back into the tranny is the LAST thing you want to do... PITA!

Cheers to you for gettin' 'er done!

Final update.... I got it!!!!!


Faulty brand new solenoid! It would not allow a down shift out of fourth when coming to a stop. solenoid "A" would not dis engage all the way it was sticky...

This valve body education was worth learning but I am happy I can drive my car again!

Now I can get to mods!

update again

New throttle body has arrived!!!!!!!!!!!!!!!

I took the time during lunch to run home and install it in the car ten minute no sweat.

Took it out for a drive after having reset the computer. Just incase.

and the throttle was WAY more Crisp! But.... Still having the problem.
so to re cap....

Solenoids changed in Transmission, Throttle body changed, New air intake removed and stock replaced E-con programmer removed and still can't drive down the road stop and pull away without the car bucking. but if i pull it out of gear it works fine or if i lift from the throttle and then re- engage throttle it works fine again until the next stop?

Is it maybe a control module issue? or maybe the whole Valve body needs to be replaced? I have a hard time believing the Transmission as a whole is bad. I don't feel it binding or hear any grinding. and it doesnt slip anymore thats for sure. it just has that surge.

Ok... Update time. I replaced solenoid "D" like I was suspecting. No dice. Same problem. The only improvement I did gain was when I duplicated the issue I didn't repeat once I lifted the first time. If I lifted then put my foot down againit went fine. BUT... Now when it it lurching.... I decide to put my foot down.... I am trying to figure if it is a throttle body issue.... Well no rpm build up just the same little surge.... Let off the gas.... Then put into the gas we are one our way again. Beginning to think it is the throttle body. But I will have to wait for 2 weeks before I have a chance to check the theory.
I just can't understand why I am not getting any codes!!!! No check engine lights nothing. Agrivating

Alptbird I should probably include that the engine was put in 3 months ago. And has been running fine till the initial issue of the transmission not down shifting to 2nd when slowing to make a turn. That spurred on the solenoid swap. Also to reference your engine and trans question. I purchased the engine prepulled so I had to use my transmission. When I got this car it had a blown motor. So far I have nursed this thing back to health. And then the trans gave me fits. And here we are. As for the throttle body I ordered one 3 weeks ago and they are on national back order till may. Good thing the focus isn't my daily driver.

As for other tests that I can do I haven't had the opportunity to do any of it yet. Easter apparently I have to do stuff with family.... :(

Edit: no codes showing I check every chance i get or test drive of 15 min or more

whynotthinkwhynot Have you checked to see what DTCs are appearing- if any? Perhaps the problem is not the transmission, but just seems to be. Maybe the reason it is surging without power once you come to a stop the first time is because the idle is simply not high enough. Your symptoms are typical TPS symptoms. I doubt that a TBS of 69k or 34k miles would be bad, but it certainly isn't unheard of. Can you verify that the part is a factory part, and what that factory part number is. It seems strange that your engine was swapped without swapping the transmission at the same time. IMO it would've been worth the shop's time to swap both from a wrecked vehicle, then sell trans from the car whether the customer wanted to pay extra for it or not. It would certainly save labor to remove both as a single unit. Then again, I've been wondering WTF most people are thinking these days anyway- stupidity seems globally rampant. Another explanation is that the donor vehicle was a MT, and if that is the case, then the TB would have to be swapped from the old engine or it wouldn't hook up to the AT. Have you verified that you have an AT TB installed? On an 09, it should have 2 cables attached- one for Cruise, and one for the kickdown linkage.

OH crap, that reminds me..... you have the freaking electric TB. Your TB could be the problem. We have seen that several times and it is more likely to happen earlier on in the car's life.

GreySkorpion Well if solenoid "D" was a refurbished one, I would seriously consider it a culprit per the link with the operations of each solenoid. This stuff can be tricky, and you provide excellent information!
