What is the word on these places that power flush your transmission? I have only dropped the pan and changed fluid and filter.

I have 1994 Ford 150 5.8L E4OD transmission.

Have I missed hidding in New Mexcio for too many years.

Any reply helpful?/

Thanks

I haven't done this... but I've heard it's a bit pricey. On my E40D in my Expedition, I have a small bolt on my Torque converter that will drain it. That and dropping the pan will get a good 90+% of all your fluid out. The trick is to line up the bolt with the tiny inspection hole on the bottom of the bellhousing.

The E40D in my 96 5.8L Bronco was never the same after the transmission flush. Shifting problems from 1-2.

Dealer did not notice it when I traded it in for my Screw.

 

I also was wondering about this power flush process. I prefer to do my own maintenance. I buy my own (premium) fluids and parts, and if I try to take those to a mechanic they want to charge me the full price for their service (which normally includes their parts which I'm not receiving).

So I inquired about a power flush kit at AutoZone, but the guy behind the counter said they didn't sell them, and some old guy behind me said, "Don't let them hook that machine up to your vehicle. That'll screw it up. Just drop the pan, let the fluid drain, and fill it back up." But the man looked a little like he might be crazy or senile, and I wasn't in the best part of town anyway, so I don't know how good his advice is. I'm also not a transmission mechanic, though.

It does make sense to me, however, that all of the crap in the transmission isn't going to just fall out with the old fluid, and the fluid in the lines and auxiliary cooler aren't going to drain, either. So it makes sense that a power flush would be occasionally necessary to thoroughly clean to transmission. I've also only heard excellent reviews from two people I actually know who have had this done to their vehicles.

So, more comments from people who have had this done, and from people who have done this themselves, would be excellent input and much appreciated.

Thanks in advance.

 

Flushing it is by far the best way to do it. If you just drop the pan, you get less than half of it out, if yu drain the converter and drop the pan, you get most of it, but in a 4R100 there are about 2 quarts left in the wormtrail and the clutches. Transmissions built after 8-11-2001 don't have a drain on the converter, so for some people that's not an option. The machine won't hurt it at all, this is one fo those times that the new way to do it really is better.

So, if I wanted Red Line D4 in my tranny, how many bottles would I need to bring to the shop for them to flush and fill the transmission?

Also, is there a chain shop that can do this well, or would you recommend taking it to a dealer only (and would a dealer be willing to put the Red Line in my transmission)?

With that old of a tranny, I would be afraid to power flush it! If it ain't broke don't fix it! Just drain the pan and the TC.
