Frens Automotive LLC Dealership sold me a Van with bad transmission Waupun Wisconsin

When I drove the Van from dealership, it drove fine.  I didn't notice any problems and no dashboard lights.  Everything was working like it should (10/05/2020)

10/07/2020 - I purchase 2 new front tires from Chets CarCare Center.

10/10/2020 Drove to milwaukee in the morning.  Van was still working fine.  On the way home, the engine light came on. 

I stop and check my gas cap to see if it was not closed all the way.  It check out fine.

I started heading home and engine light was still on.  As I got about 50 miles near Madison, the engine temp red light came on.  I stop by a gas station and filled up on fuel.  After I was done, the engine temp light went away.  But the solid yellow engine light was still on.

The next day Sunday.  I mesg Levi Frens at 7:19pm.  I told him about the situation.  He said he couldn't tell me why it did that.  He drove the van around and made sure it was working 100%.  He told me, it could be the thermostat that is going bad and that will make the engine light come on.  He then reminds me that he sold the Van to me as is. 

I told him, Monday 10/12/2020 I'll be taking the van to an auto part store and have them run a diagnose on the dashboard.  He replied back saying, you can tell me what it is, but I did sell it to you as is.  and apologized again that the van has problems. 

10/12/2020  Monday, I took the van to AutoZone and borrow their tester.  The tester came back with a code  P0740 Torque Converter Clutch Solenoid Circuit.  I immediately text Levi Frens and told him the problem.  He ask if the Van shift good.  I told him, it drives fine, from zero to 40.  But when I hit 45 to 60, the van shudder alittle.  I mesg him the picture of the print out code paper and he apologize and said it never gave him any problems.  Later that evening, I ask if he's able to help me with this.  His reply was "I'm sorry but it was as is condition.  You signed the terms to agreed on”
