Ok so im just wondering if anyone else has had this problem with cobalt. So i was driving to houston about six hours from where i live. Around half way there my cars tranny just started slipping it just wouldnt accelerate. Check engine light turned on. I turned it off disconnected battery let it cool down and the car still wouldnt move just rev.disconnected shift kit (b&m) followed same process but after that it would accelerate then slip. In order to move car had to turn it off on neutral while moving turn on put on drive quick and floor it. When i reach around 40 it started redlining. After a while i was able to pick it to 70 by turning it off and then on then just floor it. Enging code p1818 i need to know should i go with a new transmission or is it fixable???? Sorry for long story

 

would help if you put what type of cobalt you have

 

P1818 Transmission Fluid Pressure (TFP) Valve Position Switch Indicates Drive without Drive Ratio -TCM

Got that from the DTC thread not sure if its for your cars year

 

Its a 2006 2.2 auto cobalt

 

How would you fix that can it be my excuse to get my car tuned

 

Im far from being a mechanic but im guessing youre low on transmission fluid or something like that? I could be way off. andd whats your car look like? maybe ive seen you around here lol

 

Blue green with a silver stripe on the hood psp on the back lol your from the rgv

 

Yeah from pharr. dont think ive seen that car around lol

 

I took it to mechaninc a while back he checked the oil and it looked like mud he added a quart didnt do any good. O well i think i kind of shouldve seen this coming havent had an tansmission oil change since i got it back in 07.

 

Same here man close to raiders highschool.

 

Im all the way south lol in las milpas

 

I'm seeing some suggestions already as to what might need to be done with the vehicle; if you were to work with a dealership on this, please be sure to let me know! I understand, however, that that isn't always an option.

Tranny is done bro, get it rebuilt or get a new one.

 

yea i figured thanks is 250 a good price for a used tranny with only 13k miles.

 

how many miles is on ur trany right now

 

Your ATF looked like mud so you added more in?
The problem with this car is the owner.
NO this does NOT give you the excuse to get it tuned.

In all seriousness, I would take that car to the GM dealership. They will provide you with the best customer service for someone with your skil set in vehicle maintenance.

 

Its getting close to 90k.

 

wow ur tranny should not be going out at 90k...either yourself or a previous driver has really been rough on it

 

it sounds like you are low or out of tranny fluid. and from the sounds of your post you have been very rough with your tranny (the shift kit and the switching on and off and going through gears at 40-70 mph). Id say first check your ATF, fill it, and see if that does anything for you.....although it might just put off getting a new one for awhile.

 

and i thought the transmission case was sealed? or is that only for 07 and up?

 

cooler lines leak alot
