I recently noticed that my 95 850 turbo is leaking transmission fluid from a unit located on the driver's side (right side when standing facing front of car) just behind that plastic shield. Any ideas what i'm speaking of? If so what's the name of that unit and where best to purchase it?

 

I'm not sure, but my gearbox developed a slow leak after my ECU Remap...so I got my cement out, and started patching things up...

The leak is there, but really minute. I check it every time I have to hit the road. Gotta stay on top of it.

 

My check engine light came on, along with the abs light(which come on quite often) & that yellow arrow

 

The right side of the car is the side on your right as you sit in it. The left is the left as you sit in it. There is no "side" as you stand in front unless you just want to rewrite everything and confuse almost everyone.

You have a self diagnostic panel (or you should) under the hood which will allow you to read the trouble codes for the check engine light and for the ABS. Once you have codes, post them but you may want to start a new thread as this one is for transmission leak. You should try to keep a posting on topic whenever possible and the people who can best help you with codes may not be looking in transmission leaks.

That or take it in and have someone read and reset them for you. Read the codes and write them down. Reset the codes and then see if they reset again. If they do you have a problem that needs to be addressed.

I'm not sure what area you are describing with the transmission leak but someone else might.

 

I have taken care of your title so don't worry about starting a new post.

As for the leak, if you do not see fluid dripping out of something, assume you have blow by drops on that part. Leaks are pretty hard to find under the hood, especially when looking from the bottom. The winds just blows stuff all around, so does the fan.

What I suggest you do it first off, read the codes like Kiss said. Then check your tranny level according to the owners manual. If the fluid is low, which it likely is, just add a little at a time. It doesn't sound like it's slipping so you're in good shape so far. Wipe everything down, start the car and see if you can see a little fluid dripping. You may need to drive it up on ramps to get under it.

My guess is that you have a radiator leak. It does hold transmission fluid. Once the transmission gets a little low it can start missing it shift points and cause the codes, which is a good thing. Makes you find the problem.

Let us know what your codes are and look real hard for the leak. I would hope for a radiator leak if it were me, transmissions are expensive to replace. I have one if you need one.

 

Here are the codes I pulled from the A1 socket I got 1-4-3 and the A3 socket I got 2-1-3
Here are 2 pics showing the leak

 

Here is another pic

 

Man, I don't even see a drop. That looks a little wet but that's about it. See if you can figure out what those codes are.

 

The hoses are crimped to metal at each end. It might be the hose to metal pipe crimp joint that is leaking down the pipe onto that area. Best thing to do is slide a pan under it to catch the run off and spray it down with carburetor or brake cleaner to rinse the oil off. That way you can keep an eye on that area and see where it starts to leak from. You could use engine cleaner too but you'd have to rinse it off with water to get it as dry.

143 Kickdown switch faulty or short to ground

Kickdown switch, located at firewall on accelerator cable,
sends input signal to TCM when accelerator pedal is fully depressed.
TCM uses input signal for controlling transaxle downshifting and
torque converter lock-up.

I'm trying to see what part my pic represents in that diagram provided above.(1) Is it this part? (2) Concerning the kick down switch do I have to buy a new accelerator cable or is there some way for me to clean contacts or something?
