727 question for trans specialists.. #1334778 11/13/12 02:51 PM 11/13/12 02:51 PM

Well the trans guy comes back and says it needs this.. and it needs that.. and we ended up getting a complete freshen up on the trans.. One year later, we put the trans in and there is no fluid circulating... the TC level is the same and there is no fluid in the cooler and we have no forward or backwards gears.. So the trans came out and is now at the trans shop for inspection.. When we dropped it off, the one thing the trans guy says is kinda sticking with me... "It could be the pressure regulator"... except the trans was working 100% fine when it was last pulled and having the inspection done was only a precaution.. Since I know very little about how a trans works, what are some of the things I should be prepared for when I stop in later today to check on its progress.. Thanks in advance.. 73 Duster 360 stroker http://www.cardomain.com/ride/2594657

That was my first thought too after I read your converter was seated and no tangs broken on the converter or pump. Could you hear any buzzing coming from the VB area?

That's why it says to check level in neutral. Anybody that does a 727 rebuild, knows how to pressure check everything before they put the valve body in. The valve body itself, or casing could of cracked from being over tq'ed. Or it could of been warped and not setting flat if tightend wrong. A valve sticking in the VB or things of the sort. I would of thought one of the pro's would have chimed in for you by now. The wrong type of seal will also cause havock. I am just a novice, but 40 yrs playing with mopars and watching friends build them has been a plus. Seen lots of times a 50 cent o ring will stop it dead

It may be pumping, but to somewhere, the level will not drop. It is the same in park as with the engine turned off. It will read over full.

The owner told me he could not find anything wrong and he said he checked everything real close.. The one thing we both noted is the Red Line synthetic trans fluid we used turned from a strawberry soda look... into a cloudy milky strawberry soda.. I figured the oil probably aerated and it was actually foamy.. but I guess thats not the case.. The trans guy said thats common when water is introduced, but there is no way water can get into the trans as it has a separate trans cooler.. Anyways, we're putting the trans in tomorrow and we'll see what we'll see.. 73 Duster 360 stroker http://www.cardomain.com/ride/2594657

Make sure your level is right at the add 1 pint line when running cold. I had the same problem and found the o ring on the filter was not seated correctly on the valvebody causing the transmission to suck air.Make sure you got enough fluid. Your fluid should not look milky unless he used the wrong band on your drum.

Drop in, no forcing or driving it in Depending on which shifter you have it may not drop into reverse or park but make sure the shifter cable is adjusted so it will drop into nuetral and all three forward gears Mr.Cab Racing and winning with Mopars since 1964.

Of course the pump is pumping anytime the eng is running but in park the fluid is not pumping thru the circuits or cooler as its pumping back to the sump and the fluid level does not drop. Thats why most factory 727-904 dipsticks will say......check fluid level in neutral with eng running. In park the fluid level will read higher then in neutral since in park the pump is pumping its fluid right back into the sump. I have seen cars with the trans fluid level almost a qt low because the fluid was checked in park instead of neutral. There are aftermarket kits to modify the valve body so it will flow the fluid thru the cooler and circuits in park that can be installed. Thats why if your 727 sits for days and has the normal converter drainback many have when you start it and put it in gear it wont go in gear right away but if you start it in neutral or go right to neutral before you put it in gear it will then go right in gear since the fluid flows in neutral and will fill the converter right up but it will not fill the converter in park.
