Are there any common places that the transmissions leak?

 

Pan gasket, front seal, output seal, dipstick tube seal, accumulator seal, shift control seal. Did I miss any?

 

Speedometer fitting. The cable for 'kickdown' or Throttle Valve cable if applicable and the cooler lines.

Are we talking expensive to have fixed?

 

It all depends on which part is causing the leak. Some of these potential leak areas can be done with the transmission in the car...but the front pump seal leaking would require the transmission being removed and serviced.

I would not be so worried about the leak(s) as much if that when the pan is dropped...the amount of clutch material stuck on the bottom of the pan. I am not writing that I do not care if it leaks...I DO...but if the amount of clutch material in the pan is excessive....due to lack of maintenance...then I would be worried that the transmission can go out due to the neglect of maintenance. Especially if the fluid that came out of the transmission was thrown away and not saved and changed with fresh fluid...which in many cases...can cause the transmission to go out due to 'thinning' out the fluid that is still in the system. Doing a pan gasket and filter can cause you to pull out about 4 quarts of fluid. If you throw that away....the transmission holds about 12 quarts of fluid. SO ...basically you are replacing 33% of the fluid with new fluid which can change how the viscosity of the fluid is....and knowing that transmission fluid is highly detergent...it can cause for parts in the transmission that were 'happy' with a thicker fluid...now have a thinner fluid that is cleaning it further...can cause for these parts to slip and that is the beginning of the end.

I know it seems crazy...but if you drop the pan and it has a thick layer of clutch material on the bottom of the pan...make sure you save the fluid...and put it back in. The damage is already done and this will buy you time. I also put some of the old fluid in the pan. Get the clutch material on the bottom of the pan to mix in with the fluid to thicken it...I get it mixed VERY WELL...then I use a couple of my paint strainers and filter it back into the transmission. This process has allowed some of my customers to get some more time to save up the $$$ and then get it rebuilt....because I have seen that replacing that 4 quarts of fluid on a daily driver...in that bad of condition...caused the transmission to go out in less than a month.

And the TCS switch. Right at the base of the dipstick tube. If it has one. Leak like crazy in 3rd gear.

 

Do you have a leak?

 

Yes. There is fluid under the car every morning.

 

If you can not find the leak yourself. By cleaning off the transmission and getting it dry and then driving it and see where you have the leak...it may need to go to someone who can find the leak for you. It can be an easy fix or a cluster.

Thank you for your help guys. I appreciate it.

 

If you can get under it, clean it off with Brake Cleaner in a spray can. Then I hit it with spray powder, like athletes foot powder, and take a short drive and look for leaks.

 

I had the front end raised off the ground for about threes weeks doing some owrk on the headkight accuators and just found a puddle of fluid (transmission) fluid under the car.
Is it leaking from the rear seal all of a sudden?

 

Could have leaked out to bad part of seal level previously. Raising the front would send more fluid to the back, raising level of fluid to bad part of seal… again.
