Too Many Error Codes
Basically just got a 2008 HHR SS, automatic with 105k. When purchased it appeared to be in good condition, aside from some slight transmission pan leaking. Had the gasket replaced, hasn't been leaking. However the dealer cleared the codes in attempt to get the car off easily, after a full acceleration pull or two it went into limp mode and the following codes are reading:
P0700 - Transmission Control System (MIL Request)
P0335 - Crankshaft Position Sensor A Circuit
P0741 - Torque Converter Clutch Solenoid Circuit Performance or Stuck Off
P0700 - Transmission Control System (MIL Request)
P0741 - Torque Converter Clutch Solenoid Circuit Performance or Stuck Off
P0299 - Turbo / Super Charger Underboost
The car will initially off first start, put ~6 - 8 pounds of boost out, then shift into second, then it will lock up in second and won't shift until you let off the gas. After it dumps the boost the first time, it won't build boost anymore. I'm wondering if anyone has had any similar issues, or what the solution is. Initial thought was the boost system leaking or a problem with the wastegate. When the codes were checked there was no "part" recommended to replace, or even a possibly solution suggested. I was hoping maybe there was a technician lurking around here, or someone who knows a thing or two who could help weigh in, even if you only know the solution to one of the codes or have an idea. I'm really open to anything. It seems like a computer thing, like the computer is dumping the boost, or forcing it to stay in gear and not keep going. Maybe another precaution of limp mode? Considering it suspects something wrong.
If anyone needs more details, feel free to ask.

It looks like you have at least 2 separate issues.
When they replaced the pan gasket, they may not have put the correct amount of fluid in. Or there may be a damaged wire for the TCC solenoid.
For P0355 https://www.obd-codes.com/p0335
Fixing these may dismiss the turbo underboost code.
