Has anyone replaced their tranny filter and fluid on a '97. I know there are 3 filters but how do you change them and how many quarts of fluid do I need and what is the best one to use. I've heard that there isn't a tranny gasket, if not what do you use. Any help would be greatly appreciated.

yeah I have
all you do is pull off the pan but be careful you dont want fluid all over you, then replace the filters, they are right there, and the pull right off and just put them back on the way you took them off, reallly easy. just make sure when you tighten the pan back on make the bolts snug, then about a week later make sure they are tight.

Thanks for the info., do you know how many quarts of trans. fluid I need. Are there any ban ajustments? Should I use synthentic fluid?

Dropping the tranny pan does not drain 100% of the tranny fluid. It only drains about 30% - 40% when you drop the tranny pan.
It is not good to put synthetic tranny fluid if you still have about 60% - 70% regular tranny fluid. There is a tool you can purchase where you can completely drain the whole tranny fluid while introducing a new tranny fluid either regular tranny fluid or synthetic fluid. Changing from one tranny fluid type to another type requires that the old tranny fluid be completely drained out.
This tool connects to the tranny cooler lines. This tool is already filled with a new tranny fluid and you start the vehicle then the old tranny fluid goes in to this tool via bladder type and as it fills up then it pushes the new tranny fluid into the tranny system. I recommend that tool because the new tranny fluid is introduced in the correct direction and it is not forced with a high pressure.
Most automotive shops uses a reverse flow tranny fluid flush machine. It introduces the new tranny fluid in a reverse direction to get rid of the dirt and gunk from the filters. They said it is good but I don't recommend it because the seals might get messed up with reverse flow of the tranny fluid.
If you just want to drop the tranny pan, then replace the tranny filter, clean the magnet on the tranny pan and clean the tranny pan clean. I would recommend to use a torque wrench to tighten the bolts. The Torque wrench I recommend is the one that clicks when the specified torque is reached.
When you put a new tranny fluid, measure it after each time you put the new tranny fluid. When it is between min and max level, start the vehicle and let it IDLE for 5 minutes, look underneath to make sure that the tranny fluid is not dripping. While Idling, put the tranny gear to all gears and back to park (automatic) and while still idling, check and measure the tranny fluid level and top it off to make sure it is within the min and max level.
Drive the vehicle around the block a few times and then put the vehicle in park and then measure the tranny fluid level again.

Thank you, since I'm doing it myself I'm going to use a good grade of regular tranny fluid (any suggestions). I Googled the 4T80E tranny, led me to site, said the tranny needs 7 quarts to refill when just the pan is dropped. Does that sound right to you.

I've heard transmission fluid is about like motor oil. As long as it meets the latest specs you can buy whatever you want. Name brands just cost more.
