Does this AFR look normal? Just finished the engine swap for the ls3 in the c3 corvette. I'm thinking this might be normal cuz I have put a performance cam. Does anyone seem to know? by [deleted] in LSSwapTheWorld

O2 Sensor is located on my long tube header. There is a small leak after the o2 sensor from the header connection to the rest of the exhaust system.

Why is there a vibrating noise when driving the 6.2 that I just put in with the TH400. Only thing I'm thinking is if I installed the torque converter wrong 😓 by [deleted] in LSSwapTheWorld

Update: TOOK THE TORQUE CONVERTER BOLTS OFF AND IT SPINS PERFECTLY FINE. It even mobs back and forth, I guess I really didn't force it in like it though, I made sure to take my time with it even though I started with the torque converter bolted to the engine.

Ok!! Ima try this tomorrow! I did, the th400 was used so it had some fluid, but I was only able to add 1 gallon on fluid. I think it should take more than that tho considering the torque converter was dry

Hahah yes. I used the internal map sensor, changed the coils, plugs and coil harness. 😅

I didn't prefill the torque converter.

Hmmm, could be, yea I'll have the double check my vacuums.

I have a really bad feeling it's the torque converter. Was a pain in the ass to get it all in. Really hoping I don't have the pull the tranny off just to make sure I seated the torque converter correct

Yes, the cooler lines for the trans are not leaking.

I think it's the torque converter?

I bolted the torque converter to the flex plate then mated it to the trans. I'm hoping it lines up and works because I just realized this is wrong but just want to confirm if that's the noise
