I purchased a Dorman Deep Pan part # 265-811 for a 4L60E. The price was right $43.99 and free shipping. It is a nice looking price. I was afraid that for that price it would be light weight, but it is just as thick as the stock pan and has a nice powder coat finish.

My only concern is that it does not have the notch on the pan rail to vent the 2/4 servo exhaust fluid. Has anyone else used this pan and was that a problem? I guess I can notch the trans case from the inside to the fluid exhaust hole and that would take care if it is a problem.
