Driveline Slam

After going through a fairly large puddle of water, I got water in my engine, which caused a misfire. The misfire went away after I stopped and restarted the engine. Now, when in 6th gear with the torque converter locked at around 1500rpm or less, my whole truck driveline slams. It’s so hard that all my interior creaks. Mass air flow sensor? Torque converter? Water on tcm? Carrier bearing? Tranny itself? No misfire codes by the way.

 

Water in the transmission? Have you looked at the fluid?

A deep scan with a good scan tool? Check engine might not be on but a code still be in one of the ECUs. Techstream should see all that. Worth double checking,
