as you face the engine the thermostat bell is on the right (drivers side) Follow the radiatoe hose. Remove the two bolts and raise the bell still attatched to the hose. the thermostat is there with the rubber seal. You can gently pry the thermostat out with a screwdriver or something similar. Put in new thermostat be sure it is the same as the old one, and then replace or change the seal (be sure it is the smae size and thickness as the old one as I got the wrong size from Napa) Then replace the bell, and tighten, but not over tighten. I hope this helps!

this trans is the 4T65E. It needs a 4th clutch hub. The splines strip off around 120k or more because they weren't hardened from the factory. The new ones have the hardened splines. The trans needs to come out and be partially torn down. I've fixed alot of these. Change the EPC solenoid while you are there. They wear and hang up causing intermittent harsh shifts
You can drive them forever without changing the hub but you'll never have 4th gear

It's under the hood, on the driver's side, under a square, black box with a lightning symbol on it. Loosen the flower-shaped screw that holds the lid of the box down, remove the lid, flip it upside down and when you look at the inside of the lid, you'll see a map of all your car's fuses. There's also a fuse diagram on the very end of the dash, but it's accessible only when you open the driver's side door. When you're driving, that end of the dash is blocked by the closed door.

If you want to repair the oil pan I would also check lower engine mount for leaking oil and cracks in anti sway bar near fitting's. This due to engine mount is oil filled. OEM sway bar is made of tubular steel and they crack easy. Replacement sway bar is solid steel. Here's the kicker. When they pull the lower frame to service oil pan. The engine mount and sway bar are attached to that frame. A honest mechanic should only charge for parts ($35 for mount and $100 for sway bar) and maybe a extra hour. My mechanic did all in 5 hours. FYI gasket is only $35 bucks. Good luck
