Yes I am kinda new here..Most of my story can be found here..

In short it's a 96 LX I parked the car shortly after replacing the tranny with one I preformed a mild J mod to and installing a 03 Explorer motor...Drove it for a short time and tranny fluid was boiling out the dip stick tube.. So I gave up..


Now I was out installing my new super tranny cooler from Rob but to install it I first had to remove the little one I already had..When I unhooked the lines to drain what was in the cooler and what came out was milky white yes almost like a strawberry milkshake...So is this water in the tranny?? If so how did it get there???

What to do now? I have the new cooler installed and I'm guessing I need to drop the pan and install a new filter anything else???

Any help would be great...

Thanks!!!!!!!!!!!!!!!

Could be the cooler inside your rad cracked, letting coolant mix with the trans fluid. Since you have the external cooler, bypass the one in the rad completely, and then pressure test the rad to see if coolant is leaking out the fittings where the trans fluid went in. If it is, just plug off the 2 trans cooler fittings and then change the coolant and the trans fluid and filter.

Usually yes, and if you keep driving it I'm sure you eventually would, if that is indeed what is wrong, but since the car has been sitting for a while and hasn't been driven much since getting it back up and running, the conditions might not have been right yet to push enough trans fluid into the coolant for you to notice. One thing you would definitely notice though would be loosing coolant. Has it been going down mysteriously and you can't find a leak? If not, then it probably isn't the heat exchanger, but short of pouring water down the dipstick tube, I can't think of any other way to get it into the trans.

This car has never lost any coolant that I know of.I drove it for a few years before I swapped the motor out..Now it is full and as green as the day I poured it in..I find it hard to believe that the radiator would fail at the same time as the engine swap but stranger things have happened....

Been reading other posts of folks talking about when to change the tranny fluid and pink tranny fluid does not seem to be a bad thing..

I think I will drain and replace the filter and fluid and give it some road time... I know the tranny and motor have less than 1000 miles on it since the swap...

At least Mec V is a lot cheaper then it was when I bought my first case.....

Thanks for all the input and please keep it coming.....

This happened to mine. Make sure you drain the torque converter and the lines. Mine showed no signs in the coolant but I changed the radiator anyway and did not have anymore problem. Short of pressure washing the engine I don't see how the water could get in there.

Thanks and will do...

If I do decide to bypass the radiator does anyone know where I can get plugs for the tranny lines???

Any auto parts store should have them. Just take the end of the line with the nut attached to them, and they should be able to match up the threads. Or, just take the nut off the lines, weld the centers of them shut, and put them back in. Usually bypassing the heat exchanger doesn't require plugging those holes, but if it is leaking, then you will end up with coolant leaking out through them, so that is why you would need to plug them.

Water in the transmission can do major damage, get the fluid out and changed immediately, as much as you can get. All the glues used to bond the transmission frictions,bands and torque converter clutch lining are water soluble.

That means there are still 2-3 quarts of old fluid in it. I'd drive it a little and change it again. Using cheap stuff the first time wouldn't have been a bad idea to save money but if you are dealing with a stock roller clutch transmission any money spent on it could be a waste from the get go.

No I just stopped at 10 to let all the oil run off the inside of the tube so I can get a good reading...It's like 100 outside again today and I was ready for some ac...O and it is still on ramps..I wont try for a real reading till it is on level ground....

Ok so I put 11 quarts in so I need to drain it again in a few weeks and put all new...I can do that..As for the tranny itself I drove it for about 30 min or so,stopped for fuel and s six pack of fat tire..I had it on the highway and back roads OD on and off and I was not trying to kill it but I was not easy on it either...

Man I forgot how much I like this car...

O back on topic...When I parked at the house and got out the first thing I noticed was a weird smell not like the clutches but more like dust burning off the ole girl after sitting so long.. Like a idiot I reached down and put my hand on the new tranny cooler to see if it was hot and of coarse it was. I then looked to see if I had any leaks and all look fine so I pulled the dipstick to check the tranny fluid and it had a funny smell not brunt and I didn't think it was the clutches but it may have been...I did get the usually check engine so I read the codes and it was the same ole 135 and 155 O2 sensor heater circuit malfunction.. So I guess it is time to break down and get some new ones...

The tranny has a mild J mod and it still seemed to shift the same as it did.If I just drive it shifts firm if I am on it a little it will chirp 2nd and if I'm on it hard it will slip sideways a little when it chirps into 2nd..What has me concerned the most was how loose it feels compared to the fwd pos I have been driving of late and how quite the pipes are..I see new lower springs and true duals in the future..

All in all I was happy today but only time will tell...It will only get a few miles on it on the weekends so I have no idea how long to give it till I think all is well...

Thanks for all your help!!!!!!!!!!!!! I will keep you folks posted...

I guess the converter has failed...Making a humming sound at idle that goes away while driving..Well it goes away as long as I'm on the gas as soon as I let off it starts back up..I also just today replaced the IAC because it would stall when shifting into gear but it did not help..I thought I have read on here about a bad converter causing the same symptoms can this be???


Again link to sound..

I bet the water took the lining off the converter clutch, they are very sensitive to water. The glue used to bond them is water based.

All of the transmissions frictions are bonded using the same method. My vote is late model transmission, a couple hundred in changes to it and install it. For the performance edge on a budget get a markviii flexplate on car-part.com and install an 11&1/4 diameter converter. Call me at 513 898 1580 and I will help you figure out what would be best for you. It doesn't sound like you need a race transmission, most shops will charge you around $1500 to rebuild that stock transmission, I think a late transmission is money better spent.
