Transmission fluid change

[Ford ST]

The automatic transmissions routinely failed. The cooler they were run, the more you tweaked the line pressures, the longer they lasted. I still would never spend money on an automatic transmission. The manual trans in that car were extremely reliable. Only work I had to do was on the hydraulics, specifically the master cylinder.

It was a manual.

Someone who had it couldn't drive a stick and/or failed to service the hydraulic system on that transmission. That'd be the only way one could fail those. Posts on FEOA were quite rare, and never recall one saying the blew a hole in one. Extremely reliable...

I'm not going to argue with you man, I had the car for 4 years it was a certified piece of shit. The guy who had it before me blew the transmission to pieces. He put a junkyard one in it first gear synchronizer never worked. I blew a hole through that transmission. I was just cruising down the interstate and boom smoke everywhere. Pulled the transmission hole the size of my hand right next to the input shaft. That car shredded timing belts, cooked alternators, and set check engine lights off like no tomorrow. 96 Ford Escort. That car taught me a life lesson don't throw money at junk.

It may have looked, seemed, and even smelled 'fresh' and red, but that does NOT mean it was not sheared to all hell, and subsequently 'worn out'.

It will NOT get filthy like engine oil since there is no combustion blowby, nor any other dirt entering the sealed system (I believe that our vent tube has a one way check valve on the end??).
Of course, looking dirty (OR 'clean') is not even a good indicator for engine oil being '"still good" EITHER.

Engines, automatic transmissions, wet clutches and cooling systems are all different animals.

It was a dry clutch. Like many modern passenger autos, it used ATF even though it was a manual. Unlike autos, they're not subject to extreme temperatures when driven hard; nor does it (the fluid) have to serve as hydraulic fluid. With exception to coolant, particulate matter and debris, is the primary reason we change fluids. In other words, it was perfectly fine, left untouched. Trans remained quiet and engaged smoothly throughout. I changed the engine oil based on appearances and/or 3k intervals; the engine had ~86% of the book's original peak compression with ~300k.

YA, gear shear oils worst enemy, looks good, reminds me of my buddy that checked his battery's with a test light.

Might use some 15w50 in mi e when i change it.

Why? Use Ravenol 75w80 mt-2 or motul 300....both approved fluids and thicker also both have noticeable shifting characteristics.

I used 15w50 engine oil in my modded focus with a 2.3L swap. It ran perfectly fine and much smoother than the stock "water" from factory.

Tell me of this 75w80?

Yes, it is actually MADE FOR manual synchronized gear boxes, with all of the proper requisite friction modifiers, and other additives, as well as a VERY stout base stock makeup over ANY engine oil.

So you do not believe that there is ANY actual mechanical shear happening in a manual transaxle?!?!

Yes. Just drop some Prestone (make sure it's the heavy duty) in there and it'll be fine.

he's worried about '''''''''''' ? sorry i deleted the insults

Transmission fluid is like motor oil. Everyone has a favorite and nobody has any real data other than ad copy. A good reason for me to stick with what the people that made it and warrant it specifies.

Did you ever think they would use the cheapest oil they can get away with that meets spec? they take it down to the last penny. that penny could be their job.
