I found huge amount of Transmission Oil in the pressurize coolant reserve. I think it came from the trans oil because I found a corrosion on it. Do I need to replace the oil cooler and radiator?

 

def radiator, if the trans fluid wasn't poured in there, but make sure your trans fluid in your tranny isn't pink, if it is it will cause tranny failure.

 

What should be the color? I'm using the red or maybe pink oil. Are you referring to unused tranny oil color? Yeah, I'm having problem with my transmission. What should I do?

 

Yeah, that may end up being a big problem. The only ways to get transmission fluid in the coolant is either someone put it there or the in-tank transmission cooler in the radiator is leaking.

Definitely make sure there is no coolant in the transmission fluid. If so then a flush isn't going to fix it. The paper clutch material doesn't like any water at all and if it got any at all then the damage is done and the transmission won't last.

or the trans cooler lines in rad broke-i'd put money on that

 

As of now the problem in my tranny is delayed clutch release. Shifting from P or N going to R or D takes few seconds to engage. While driving a moderate step on the brake will take few seconds before it engage. It's like the clutch is not releasing because stepping on the gas after braking will rev up like the gear is in N. Could it be a brocken accumulator spring or something even worst? If I remove a broken accumulator spring can I put it back so I can temporarily use the vehicle?

 

if you had the oil to water cooler leak inside the radiator causing tans fluid to go into the coolant...their is a GOOD possibility coolant also mixed with your transmission fluid. Is the fluid on your trans dipstick milky in color? Water in a transmission will completly destroy all the frictions and rubber seals/pistons.

 

I think so,

I can hardly see the level of fluid in the stick so I decided to add small amount of fluid. After adding and checking the stick the fluid level is now visible. I only add small amount not more than 500mL and the level is now at the maximum.

 

Why is the radiator designed this way? Seems like the result of a simple radiator failure is extreme if the trans is destroyed.

 

I don't know why they do it. But transmission coolers have been inside the radiator ever since I can remember.

 

It is to cool the transmission. The cooler in the radiator is VERY effective. Failure of this cooler is rare, but anything built by man can fail.

 

My neighbors F-150 FX4 had the trans cooler fail in the radiator and wrecked his transmission with only 17,000 miles. Ford installed a new trans and a separate trans cooler outside the radiator. This is the set up my Blazer and Jeeps have had with factory towing packages. May be efficient but the potential damage to the wallet seems high.
