Do we have a drain plug on our tranny[4r100]????????

 

No

 

It is a bit messy, I bought new filter and gasket to change my fluid. Loosened the bolts and let it dribble out the rear. It made a mess but what the heck. At least I know I got it all out and was able to have a good look inside for myself.

On my 99 there is a plug in the torque converter and was able to drain that to.

Used the old gasket when I put it back together cause I plan on changing to Amsoil tranny fluid soon. Then I will use the new gasket.

I just wanted to have a look see and didn't want to put it off any longer.
Still trying to decide if I want to put in Greg's shift kit. I would have to reburn my flip chip and sometimes I am just in the mood to poke around. Very seldom do I use the race side anyway.

 

do yourself a favor if you are changing your tranny fliud go buy a Ford 4x4 pan($30-40 i think). It has a dran plug and fits our tranny, so no mess next time around.

 

Not being a mechanical person by trade is it possible to have a drain plug installed on the stock pan (is it thick enough)? I was thinking about buying an FTVB and to avoid possible problems should a warranty issue ever come up I would just keep the stock pan.

 

Yes, it's possible. Yes, it's thick enough. You can get them at most auto part stores. B&M has sold the #80250 for over 30 years.

 

Honestly, I think they'd be more likely to raise warranty flags from having an aftermarket plug installed in a stock pan that having the deep pan with the drian plug. People here call it the 4X4 pan, but most of the 2WD models use it too, (not by models, but by numbers sold, all diesels except the DSO van get it, and about half the powerstrokes get it with 2WD I think) and most dealer techs would have to look up which pani t was supposed to have. If nothing else, if they ask, you could play ignorant, act like you have no idea what they mean, and at worst they'd think it was a mistake at the tranny plant (even though there are about 5 ways that it can't happen, again, a dealer tech wouldn't really know for sure) With all the changes they make from year to year, and even mid year, (A pillars come to mind) they wouldn't give it a minutes thought, on this paticular part, anyone who reads this board regular prolly knows better than a dealer tech anyway. Just what I think.

However, when the 4X4 vs stock pan came up some time back, you posted Ford may well be able to void tranny portion of warranty for 4 X 4 pan. Something like, ford could document "different splash pattern" or something to that effect? In spite of the mess, might it not be better to reuse stock pan when installing FTVB. Probably no tech would notice then?

 

A little different question along the same lines. When doing a fluid change at 60,000 miles, is it necessary to have a shop flush it? I have the deep pan and would like to just drain and fill. Gregg, what do you think?
