Need help with check engine light and P0740 & P0700 codes

Nice question @negro2006. Could you give some symptoms of your issue? My P0740 is becoming a Christmas Decoration! Hi @burdetter16 ....wondering if you ever solved this? thanks, Dave

I wasn't having any symptoms when I posted that so I didn't do anything until about a month ago when symptoms began to occur. I replaced my tranny fluid but that didn't fix anything. After doing some research I think it is the TCC solenoid or maybe even the torque converter itself. I decided fixing either of those is a little beyond my skill level (especially since my TJ is my only vehicle) so I am taking it to the shop in the morning :/ I report back what it is once I find out.

hey so whatever happened with this?

I haven’t had a chance to take it back to AAMCO yet. Been waiting to fix this other car so I can use it. I have cleared the code 3 times already. It drives fine in town, no symptoms or anything. The light will only comeback if driving over 60mph. Other than that, the engine light never comes up. But I will take it in soon since it is still under warranty for transmission rebuilt done during summer 2021.
