Hot Rods Water in my cast iron power glide fluid

I have flushed it a few times and it still struggles to get into gear, hit and miss. Is there any affordable way too resolve this issue?

 

Is the cooler in the radiator or is it remote? If it's in the radiator, that might be the problem, it's cracked. When you pull the dipstick, does it look like a milkshake?

 

Yep, it came from the radiator and it was milk shake.
I disconnected the hoses from the radiator and ran new fluid twice but I think it gave up the ghost!

 

Pull it, clean it out, replace the rubber seal's, and stuff it back in. Everything else is futile. Milkshake's suck... unless they come from an ice cream shop!

 

Water has a negative effect on friction materials.

 

The word I got (when I got water into my modern automatic transmission) was that the water breaks down the glue that holds the friction material to the steel plates and bands. The only fix is to replace all of the friction parts that were originally bonded to steel. If the bond has not failed yet, it will shortly. once the water made contact with the bonding agent, the process has started.

 

Correct.

 

Well, that's what I thought and you just confirmed it. Thanks guys.

 

This! I’ve done dozens of trannies for this exact reason .
Volkswagen was notorious for this in the 90’s with their “Autotragic” transmissions . Bottom of the trans looked like overcooked oatmeal when you pulled it apart .

 

X38 is correct. The lined plates will disintegrate. The rust is starting so get it apart as soon as possible if you plan to save it.

 

Short answer: no. It has to come out and be rebuilt with all new seals and friction material. You need to make sure that your rebuilder has done a cast iron Powerglide. They are a beast mainly because all the part are so heavy and you have to align a bunch of things when you go back together.

 

Maybe a good time to update to an aluminium powerglide?

 

My left nut still aches when I hear the term "cast iron PG"...

 

If it's a 235, that's not going to work. If it's a V8, and I was going to change to a different transmission, I'd go with something better than a Powerglide.
