Just got it back from the mechanic. Transmission and normal service done, check engine light is still on. Not sure what it could be. Same two error codes p1660 and p2757 so I assume these need to be checked by another mechanic. Car drives nw and feels smoother; little bit of bogging but I’m not sure. Shifting and all that is much better than before 

Just tried to put the car into reverse again to drive it to the mechanic up the road, car started shaking immediately. Not gonna risk driving it anymore, seems completely messed up. The knocking noise is gone however, rechecked the codes with my scanner and I’m still getting 2 codes.

p1660&p2757.

im not sure what to do at this stage - can’t drive it to anyone but I can’t afford for a tow truck either. From what I’ve read it seems like I definitely need a transmission fluid flush/replacement and something to do with the intake/air control & a solenoid or something. Too many issues to sort out at home lol 

Yeah stock AT-X. I’ve looked on eBay and could only find older models; not the 2014 one. I’ll keep looking though hopefully something comes up

He didn’t say much just did the scan, checked the fluid then said 5k to tow it and replace the gearbox or the tranny or whatever it was.

I know it’s history, completely fine until 85km. After 85, driven a bit rough but nothing too extraordinary. Gonna see if I can get another mechanic or auto specialist to look at it tomorrow I guess. If it is indeed a 5k process I might have to just scrap the car

I would speak to an auto transmission specialist before you do anything. I won't discount what the mechanic said, but I'd definitely get a second opinion.

When you mean "burnt oil" how bad is it. I know transmission fluid does go brownish red with time but if it has a distinct burnt smell then that car has had the life thrashed out of it or it's been used for towing. Does it have a tow bar ??

Did you get a fluid sample ? If so can you post it so we can see ?

For a car that's only done 120,000 kays that transmission should be in much better condition than that. It's been abused for sure.

I didn’t get a sample but I saw it on his hand, it was super dark brown basically black. I’m not sure about the smell but he stated “oil in transmission. Black and burnt”. No tow bar - I agree it hasn’t been treated the best but not abused. Majority of those km’s up to 85-90 it was driven like a grandmother.

Transmission fluid pressure switch & torque converter pressure switch solenoid stuck is written the paper. Mobile mechanic quoted 5k to tow and replace the gearbox? 
 

the trans fluid had burnt oil in it. Any suggestions? 

The reverse was working when I tried it just now but a clubbing noise - all roads seem to lead to spark plugs & transmission fluid. Thanks for the help guys, I’ll update tomorrow once the mobile mechanic comes with a diagnosis 

Thanks for the response, I’ll see if I can try and get under the car to take a look. Would the fluid explain why the car can’t go into reverse anymore? And a loud idle with a bit of knocking is what I noticed earlier today.

called in a mobile mechanic but they can’t come for awhile so I just want to see what I can figure out for now because I’m scared it could be a big issue 

I don’t know where to find the fluid, I’ve looked everywhere.

my car just completely stopped reversing and I can hear a knocking noise under the driver side. Put it into reverse, stays in neutral.

@campbean I’m filling it up every 2-3 days. Just checked again.

p0990 and p2757 for A/T

p1660 for engine

idont know where to look to check transmission fluid as it seems that might be an issue

Car was due for a 120,000 service 4,000kms ago but I’m tight on money at the moment so I don’t know if I should pay for a service or if there’s something else I need to do first.

check engine light and traction control lights came on a few weeks ago. fuel was draining really fast, 25-30 litres would last 2 days with basic regular driving. Now a day or two again it started jerking randomly while accelerating, when I go from a standstill the revs will keep increasing and it won’t change gears, etc. 

not sure what the issue could be. OBD2 scanner gave me engine/transmission code but nothing specific.
