4L60 is Dying!

[1TRUESS]

I knew this was going to happen to me sooner or later, but why now?! Truck will not stay in OD. I have to give it gas for it to shift in to OD, and as soon as I let off the gas, just the slightest bit, it will go right back into 3rd.

Also my 2-1 down shift feels funny. It will shift down and then shift right back up and the motor will bog. What is this all about?

Do I need a rebuild (or a 4l80) or do you thing I could have done something when I did the shift kit? It seemed all fine right after the install.

4th gear problem... when you installed the 4th servo into the cover was it hard to do? You need like a feeler gauge to install the lip seal of the 4th servo into the cover. I bet that's it or another O-ring is off.

2-1 down...elaborate more if ya could...seem like lack of line pressure? Could be an accumulator piston seal (if app), piston cracked, etc. Could be boost valve install also maybe.

What all do you plan for the truck power wise? I fully built 4L60E in a truck should be able to hold 400-450rwhp IMO, weight hurts us a lot.

OK! Drove the truck to work and back, took the highway, and the trans seems to be fine now! WTF! I am not complaining. Maybe it was just a particle working its way threw the valve body. I am not worried any more.

I am going to hold back on the truck mods for now. Well I am going to at least try to. (You know how that goes&#33 I need to buy a beater and start thinking about buying a house. BUT, in no way am I ever going to sell this truck or ever be done with it.
