Is there a good way to purge transmission fluid at home?

I desperately need to change my transmission fluid and filter, normally I don't let maintenance lapse like this but, having been out of work for over a year changed my priorities. Anyway, I need to change out my fluid and filter, both easy but, I also need to purge the transmission fluid and I was wondering if anyone knows a good way to do this at home without any special hardware.|||There is no good way to purge the transmission at home, this requires expensive specialized equipment not available to the Do-It-Yourselfer.





However you can change the fluid and filter at home. This will replace most of the transmission fluid so a purge isn't really necessary. Be prepared as this is a messy job.





Get yourself a large drain pan to catch the transmission fluid.





Place the vehicle on jack stands.





Transmissions do not have drain plugs. You need to remove the transmission pan to drain the fluid.





Loosen and remove all of the bolts except one or two on a corner. Then slowly start removing the remaining bolts a little at a time. When the seal is broken you will lose a significant amount of transmission fluid so be ready. Most of the fluid will come from the opposite corner of your remaining bolts.





After the seal has been broken continue to remove the remaining bolts and pan.





Drain the remaining fluid from the pan. There may be some metal shavings in the pan. This is normal as long as there is not an excessive amount.





Change the filter. Reinstall the pan using a new gasket. Fill the transmission with new fluid of the correct type.





Start the engine and allow the engine to reach operating temperature. Run the transmission through all of the gears on the gear selector stopping for a few seconds on each gear. Top off the transmission fluid to full.





Drive the vehicle several miles. Top off the fluid. Check for leaks.





After a week or so check the fluid level again, but it should be OK by now.|||just remove pan to drain it all you really need to do is kind of messy but not hard dont need to flush or purge it at all when one does a filter change at a shop they dont flush it either a big catch pan remove bolts one at atime let it slow drip into pan do not remove all of them or it might drop and make big mess filter nothing to it really done it a thousand times|||Yes, you can change the transmission fluid and filter at home.. You will need to have a jack to lift the car up.. Jack stands so you don't kill yourself saving dollars. And a ratchet and the right size sockets, have a large open pan to drain the fluid in, depending on your vehicle, there could be several quarts in there, especially if you have adde extra fluid hoping that would stop the transmission from slipping.. I figure since you are asking, you are having transmission issues..Anyways, to change fluid, try loosening the bolts of the pan s that you get one corner of the pan to break free first, that way the fluid will kind of be channeled into the big pan you already have under the car..This can get real messy in a hurry if you aren't careful. Also many automatics have an inspection plate between motor and tranny, you can remove this plate, and some converters have a drain plug, so you can get that fluid out as well. Look at the fluid, it brown or black, tranny fluid smells a little wierd,but does this smell burnt?? Look on the screen of the filter, see anything silvery or shiny?? espcially silvery grey crap that is stuck to filter, that is the clutch facing of the trannys internals, so your tranny might need further mech help than a simple fluid change.. If all looks good, switch out the the filters, and use a thin bead of sealer to attach gasket to pan so that it stay put whileyu get your bolts started.. This is a pain inth butt doing yourself.. I try to get one in the center of one of the sides, start that one and then get one in opposite to that, run them in about halfway, then get bolts in all four corners then fill in the blanks,try to tighten them equally t that the gasket snugs down has a whole, crank em in easy, after you feel the bolt stop, turn it aboutanothe half turn, dn't want them too tight, the gasket can split and then your tranny is gonna leak.. refill fluid, if you have some miles on this car, I would suggest a quart of LUCAS tranny fluid.. They make a good product, it will help to rvive that tranny, or if it is slipping, it might help you get some more miles on the car before you have to replace tranny,good luck.. When people talk about evacuating fluid being a fancy deal, actually they are jut using a vacuum pump o get fluid out.. You have a Kerosene siphon?? The kind that is a plasti tube with a ball on the top tha ya squeeze?? I have duct taped a length of flexible 1/2 tubing to the straight part under that ball and sucked most of the fluid outof the valve body that way..
