4l60E Trans Issue

[CountryChevy15]

Last week i turned the corner, hit the gas to accelerate after the corner, shifted perfectly fine no hesitation or issues. Let off the gas as it cruised down the road about 100 yards. Went to get back on the gas, truck high revs. Pulled over, no forward or reverse gears. No noises, leaks, or visible damage. Park holds the truck like it should. Pull both lines off the trans cooler and start the truck, should spray fluid out one line which it does NOT do. Also have a ticking noise that speeds up with engine rpm coming from the bell housing of the transmission. When i put the transmission in each gear, cable moves but there is no jolt that it went into gear.

From my lack of flow out the trans cooler lines I'm assuming the pump inside the transmission went south. That doesn't explain the ticking noise coming from the bell housing area. I'm starting to wonder if something inside the torque converter went south and isn't locking the flywheel to the torque converter.
OR
Am i looking at a transfer case issue instead?

I'm sort of at a loss of what to check out without starting to pull the transfer case and transmission out of the truck and have them taken to a local shop for diagnosis. Trans company is ignoring my calls now after my original call about it. It has 3760 miles on it with a 15,000 mile warranty. Shop is in Florida I'm in Illinois so i cant just drop by and ask for a explanation and resolution from them. So chances are I'm going to be fixing this on my dime.

Intake manifold gasket seems to go on every single van, anywhere between 60k and 150k. This van has a host of cooling/transmission issues. you can visit you repair mechanic or see some of the best mech on Illinois auto repair.

Sounds like your pump is out. i had a ticking noise come from the bell housing area when i broke my pump.

While not common on the 700R, it isn't impossible that you snapped the main shaft. The super crap T45 and 3650s do it all the time. It's weird because when they snap it doesn't appear that anything is wrong. Clutch feels good, shifter clicks in and out of the gears, no leaks or noise.

It's common for the pumps to out on these.... Sounds like your on the right track.

^^Absolutely. Just wanted to introduce another option if the 1st one isn't correct.
