    No need to flush!!! Just drain, replace the filter and pan/gasket then refill. Don't (do not!!) use 'any' sealer or glue on the pan gasket. Just use the gasket by itself!! Use quality parts as well.

    You need a machine to flush anyway!

    It can be done the old school way using the line to drain while adding fresh fluid but not necessary. Not a machine flush but about the same results. I have mixed feelings about that whole flush thing anyway. You?

    I have 2 machines and believe in it. The results show you can remove all old broke down fluid from clutches, pump, convertor all, with cleaner and conditioner even better. Just my opinion from evidence I've seen.

    Well the reason i ask is some mfg dont recommend it, like Toyota. Thay say no need to even change it under normal conditions. I disagree with that though! Just heard different opinions, like on everything else we do.

    Thank you guys for the quick response,.. I drained and fill about a month ago, but I found a leak on the plug where the Speedo cable suppose to go, since I have a speed sensor, the Speedo cable was eliminated and cap off, changing the o-ring stopped the leak, anyways considering I just changed the oil, it still seems very dark and dirty, so I'm thinking of total flush and filter change,..

    do you advice taking it to a shop or I can do it the old school way like you said draining and filling.

    Fair Enough..! well how about doing it with the Mityvac Fluid Extractor Pump? Have you heard anything about doing it that way..?! I'm thinking of buying one and connecting it to the cooler lines to suck the fluid out from there after sucking the oil out of the dipstick..

    Won't work. Need to use the trans pump to pump the fluid through.

    I see,.. Thank you very much for the help..!! I'll keep you all updated on how it goes.. btw 1 more question, I was reading about the seal on the pan,. Is it really required to put permatex on pan with a gasket, or can I just install the gasket itself..?! Any advice on this..?

    That depends on the type of gasket used and the shape of the sealing surfaces or straightness of the pan.

    I'll check it out over the weekend, but if it seems to be straight and good can I simply use the felpro rubber gasket and eliminate the sealant

    Get it clean, and don't overtighten it or it might pinch/cut the gasket. Lay the pan on a straight flat surface to insure it will seat properly. No warpage or straighten.
