So I been looking around online and have narrowed down my problem to this exact paragraph I found on an Impala forum.

"What is "limp-home mode" ? That is the street slang term for a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear."

How would I fix this problem and where would I start? Would changing just the torque converter fix this problem?

 

i had kina the same problem in mine i think, does yours act like its in neutral when try to put in 1st an 4th. my problem was 3rd an overdrive wouldnt engage, i just went ahead n replaced the trany cause it was way easier for since i was able t get one for 90 bucks from a buddy that was scrapping his

 

When I put it in 1st it's basically in 2nd because it takes off very slowly. So 2nd and 1st are the same because when I shift through those two gears manually I feel no shift. The only shift is feel is when I go into D which is 3rd. There's someone that will rebuild the tranny for around $600 but I'm a college student and a little tight on cash so I'd rather skip that if I could.

 

Anyone?
