annie1995williams Posted September 11, 2019 Share Posted September 11, 2019 I was getting on the freeway today and once I hit 4000rpm my engine entirely bogged down. Foot to the floor rpms were creeping up. It has also been shifting very hard. It seems to run fine under 4000rpm. Automatic transmission. Has anyone had this happen and figured out what it was? Thanks in advance. Sent from my SM-N950U using Tapatalk Link to comment Share on other sites More sharing options...

Tehnation Posted September 11, 2019 Share Posted September 11, 2019 If you have a scanner check to see if there is a pending code. There has to be a code.... Link to comment Share on other sites More sharing options...
Tehnation Posted September 11, 2019 Share Posted September 11, 2019 I'm not sure about automatics so I can't really say anything without a code. There might be a way to diagnose the automatic transmission ive read, i'm not sure on the details. How many miles? Link to comment Share on other sites More sharing options...

Tehnation Posted September 11, 2019 Share Posted September 11, 2019 https://legacygt.com/forums/showthread.php/reading-ess-dtc-codes-171935.html Maybe the tcm might have a code, apparently you can check it. Link to comment Share on other sites More sharing options...
Tehnation Posted September 11, 2019 Share Posted September 11, 2019 depends on your scanner or whatever I guess. Not all scanners scan tcm codes Link to comment Share on other sites More sharing options...
