Check your transmission breather hose situation. It should be on top of the bell housing to the passenger side a bit. If there's nothing there, put something there and run the hose up somewhere in the engine bay.
Something I did was route the CPS wiring down the driver's side of the transmission where I can easily unplug and remove it. The default location is routed behind the cylinder head somewhere. It's an inconvenient spot to reach.
Besides running the transmission vent hose up front, the transfer case and rear axle vent lines can also be be run to the front.
I terminated them on the passenger side to clean up the driver's side of the engine bay.
I re-routed the wires and emission hoses, over the top of the transmission, to allow better access to the CPS.
I'm in the middle of installing a stroker. Just about everything in the engine bay that has a bearing is getting rebuilt or replaced.
This includes the 17 year old fan housing bearing, a part that is impossible to find while on the road. While it still rotate smoothly, it felt dry.
The A/C's clutch bearing was noisy and was replaced.
This is a great time to clean up the electrical or to add electrical items.
My 2001's injector plugs were brittle and braking, due to heat and age.
It was nice to sit in the freshly cleaned engine while splicing in the new injector plugs, instead of bending over the fender.
With the front clip and radiator removed, its a good time to upgrade the headlight wiring and to add a transmission and/or steering cooler.
