More A4LD Problems
I have a 90 ford Aerostar 3.0. It uses the A4LD transmission. My tranny died 2 years ago so I had a rebuilt one professionally installed. It has worked fine till today. My tranny has an intermittant problem in it. It will function fine sometimes but sometimes it will slip on takeoff or at any speed. Upon takeoff it will sometimes shutter as well. I checked my fluid level and it was way too high on the stick. I changed it and noticed that it appeared slightly milky. There were some metal shavings in the pan. I took it to a shop and without even inspecting the transmission the mechanic concluded that it was defective. He then checked the fluid and said that it was burned. The fluid was not burned as it was a light red/pink color and didnt smell burned. I'm thinking torque convertor or pump. What do you think?

[updated:LAST EDITED ON 20-Sep-02 AT 09:12 PM (EST)]With the milky appearance and a fluid level that is too high, I would suspect that perhaps you have a tranny cooler leak (engine coolant leaking from radiator into the transmission line). I suppose it's possible, not sure how probable it is. Check to see if the coolant level is decreasing with no signs of external leakage.

My coolant level is decreasing and I cant find a leak so I think that the cooler is part of my problem. However, would a cooler leak cause the same symptoms that I am experiencing?

In terms of your transmission performance, I can't say for sure as it all depends on how much coolant leaked into the tranny and how long it's been there. But if coolant is leaking into the transmission lines, it can't be good and I would expect abnormal operation of some sort.

Your converter works on fluid, which is thicker than water. You add water you get foaming and slippage. Worse, if you have a coolant leak that means your engine is not going to cool properly and over the long term (say 2-3 months) you can cause hot spots and damage to your engine.
