2 3 flare and no reverse after warm up

[Flashflood]

Well here I am again I think my transmission is toast. I dropped the pan and the valve to remove a double gasket on the valve body. Put the valve body back up made sure all the bolts are tight and boom everything that I had issues with was fixed. I kept checking the fluid and made sure it full, and then i took it on a drive, but after it warmed up boom 2 3 flare and no reverse when I got to Walmart. So I think she toasted!

Sounds like a valve body gasket slipped or not tight enough

I only say that because it works fine when it's warm so there's no broken parts

Actually opposite there Donald's works fine when cooled off when warm flare and no reverse or that's what it was when I took it for a drive the first time with full fluid. I'll keep you updated.

Check your transmission temperature perhaps the coolers clogged

How would I check for a clog? And are you talking about the metal cooler lines that go the radiator or the aux cooler that the rubber lines go to. Unfortunately can't check tranny temp cause I don't have a gauge going to get one if all this gets solved.

The 1 on the top of the radiator is the pressure side The 1 on the bottom of the radiator is the return side

Do you have to remove them from the trans and what about the cooler?

 

[donalds]

I just removed them from my trans ran some cleaner through both directions
Following with compressed air

You will have to figure out where to disconnect your lines depending on rust

Be sure to use a line wrench

But I'm willing to bet with this info, and since I still get a blinking od light that my pressure line got gunk in it.
