My 07 GMC Sierra 2500HD it has 195K has started acting weird.... back story! a couple weeks ago my husband took it on a longer trip down hunting pulling a trailer he told me it was running warmer and when we get home needs a tranny service. and 2 days later it pulled the TMC P0842 code. Anyways I went ahead and got the tranny serviced and the fuel filter done too. And it’s been running great for 2 plus weeks now and last night on my way home from work as I was slowing down coming to a stop it had a hard jerk going down into gears and I slowed down and then pulled the same code again TMC P0842 and EMC P0700. This time around pulled a second code. So I guess I’m wondering if any of y’all have had this same thing? Or similar? I’m stressed out and have an appointment tomorrow. But was wondering if any of you guys know anything about it. The Tmc code says it’s the tranny pressure stabilizer. Any advice is great! Thanks

Thanks so much! I cleared them after I wrote them down last night and came to work today and it drove great! Until I was coming to a stop and it sifted hard again.... but no codes. I appreciate your response thank you!
