I haven't done any transmission work in over a year so I'm pretty rusty.
This is a big thread so I assume your reply is in regard to one of the latest questions:

I'm thinking a pump seal could possibly cause the overheated drum, but not without other noticable symptoms {depending on which seal you are refering to}, and I wouldn't think a pump seal would produce a "no 3rd, or 4th gear" symptom without affecting other hydraulic modes; {which also depend on pump pressure for proper operation}.
Can you explain in detail further?
Thanks

Cracked band drum?! How can this have happened...
by SCNGENNFTHGEN
the other day, on my way to work, about half way there, when I noticed it had no 3rd, or 4th gear. I take off, and everything is ok at first. It goes in 1st gear like normal, then shifts to 2nd no problem. Then it goes from 2nd like its going to shift, and it feels like its shifted into nuetral! It also still has reverse.
Can you explain in detail further?
Thanks

Dave,
I worked at a shop for 7 years that worked very closely with ATSG, and Sonnax Ind. Many of the products Sonnax sells now were products I helped create. The very first "Super Hold" Sonnax 4th servo prototype was in one of my 4L60E's. The very first Sonnax servo check valve was used in one of my 700's. The owner of the shop is an extremely intelligent man, who I learned alot from. I don't just pull ideas or opinions out of the air. If I have a strong opinion about something, it's because I've tested it.

Is it ED Lee possibly??

Ed is who taught me to think ahead of the crowd. He's never been comfortable with "following". There's no doubt that I'm where Im at today because of Ed Lee. Everything I learned during my time there has carried over into CPT.

Um...Nope, not the sun shell. I'd bet you're forward clutches are fried so bad that they've "welded" themselves together. This effectively means that your forward clutches are locked on. This will cause no reverse and will cause it to move forward in neutral.
This is most commonly caused by a cracked forward piston.
