Does anybody know where & how to flush & change the filter(s) on a 4-banger automatic transmission and what are the best products for a tranny over 125k miles???

I'm determined to service my slipping tranny myself before buying another used tranny and chancing it slipping or needing maintenance now or later.

I recently (Sat. Feb. 28th, 09) purchased Valvoline High-milelage AFT3 transmission fluid for vehicles over 75k miles & Lucas transmission treatment. I haven't added the drained or replenished my automatic tranny; I want to replace the filter(s) and need knowledge on how to and where are they located; please advice me and all the other DIYs who have 4-banger automatics.

1. Do 4cyl automatic tranny's have filters - y/n?
2. How many filters if there are any?
3. Locations and rating on ease of replacement
4. Can a 4cyl automatic tranny be flush - y/n?
5. If so, how and with what products?

Tranmission additive, which is better; I saw all 3 in my local AutoZone; I'm curious to know:

1. Slick50 tranny
2. CD2
3. Lucas
4. Other - please list it

What's a good automatic tranny flush product and how to flush the tranny?
