Hello you will need transmission repairs sometimes when a filter and fluid is changed when a scheduled maintenance has not been followed by owners manual you might have trouble as you do believe it or not sometimes when you exceed the suggested service millage you better off just to leave it and do not service or you can experience trouble as you are having.My solution is take your vehicle in to a transmission specialist you will need a hoist to determine the extent of your repair you might have to rebuild your transmission.

there will be a plug at the bottom of the transmission. pull the plug, let it drain, and replace the plug. Refill with the recommended amount of fluid out of the owners manual. Run the vehicle through the gears a few times with the car started. let it idle till the temp. comes up, then check the trans fluid level and add till full

Most have a drain plug on the pan. to do a simple change, just remove the plug and drain it, then re-fill. to do a filter change, you need to remove the pan and the filter inside, remove all the gasket material (or it will leak) and put everything back together. There is no provision for draining the converter so if you want to do a better more complete change, drain from plug, refill, drive a few miles to circulate new fluid, then do a complete change with filter. You won't get it all out but a considerably larger portion of the old fluid will be removed.

The dipstick is located under the air cleaner on the right-hand side, identified by a yellow ring.

You need special tools to do that plus you need to change both differentials and transfer case oil so my advise is just find a good mechanic who will do it for cheap. Thats what I just did anyways and it ended up being $240 for everything plus $50 for the special tranny fluid that I had to buy myself at the dealership.

I have a feeling you have the transmission extremely over full. I actually am pretty familiar with maintenance service. When you drain the system off the pan you only retrieve about 35% of the fluid. I would start by checking the level on the stick agian and confirm it. If its over full drain it agian and add 4 qts for starters. Start the truck and with the brake pedal compressed place gear selecter in each gear for 10 seconds then return to park and check level agian. Total transmission capacity is 9qts. and the preferred fluid is DEXRON III / MERCON.
