Hello, So I decided to replace the rear main seal due to an oil leak. I removed the skid plate, starter, exhaust, oil pan, bearing brace and then removed and replaced the seal. I then put everything back using OEM torque specs. Somehow this process has damaged my transmission. It will not go into any gear. It is on a drive up ramp and I can’t even get it in neutral to roll it off. Anybody know what I could have done to cause this? Thank you
