And the exhilaration of feeling like you've been rear-ended when it forgets to shift out of neutral in a timely fashion off a light and neutral-slams itself.

Mine's not done that, yet. Sometimes there is a very slight delay but it has never slammed into drive.
Yeah, I think that traces back to the fluid running low from the lines leaking.

I just ran into this on mine. It had been shifting extraordinarily hard ever since the weather warmed up, so I dropped the belly pan to check the level. Nothing came out when I pulled the level-setting screw! I added a half quart, expecting it to immediately drain out, but still nothing. Finally started to drip with a little more added. Turns out I was a full quart low. I was also starting to get what felt like torque converter shudder. After getting the level back up to spec and adding a tube of LubeGard Shudder Fix, it's back to shifting like its typical self. Looks like I'm going to have to replace the lines again, and add about a half-quart every 10k miles until then.
 
I think when it comes time to do the lines again, I'm either going the $5-fix route, or I'm just going to buy an external trans cooler and bypass the radiator entirely so it's never an issue again (because the radiator-side fittings are a nightmare).
 
It's just funny to me reading this about leaks. On another forum I just got into an argument with a bunch of people about how you have to set the correct level on transmission. They are convinced you can just put back in what drained out and not worry if it's the correct fluid level or not.
 
I've been keeping an eye on mine, but since I replaced the cooler lines a few years ago they haven't started leaking again.

Did you guys replace the cooler lines and they started leaking again? @revjpeterson @MP81
Mine haven't yet (that I've noticed), but they're known to spout leaks eventually (in all vehicles) just due to the design.

I mean, sure you can do that...provided you know that A) you didn't spill any and B) you're not starting with an incorrect amount to begin with. :LOL:

I replaced my lines the first time around 4yr/76k miles. They held pretty well until I noticed them leaking last fall around 10yr/240k. it took about 6mo/21k to lose the quart of fluid I found was missing this spring. It looks like it's just one crimp out of the 4 that's leaking.
 
I see GM has discontinued the part. Anyone have options for cutting the compressed fastener and installing a new one with new hoses, possibly with hydraulic hose couplers?

Also looks like you can import them from Europe for around $100 part# 39066190
 
Yeah after I posted I saw a video on YouTube where a guy did something similar. Having the barbed ends on the pipe make me feel more comfortable about cutting off the crimped fitting and using a clamp if for some reason I can't get the EU part. But so far after 120k miles since I installed them my new lines are not leaking ...yet.
 
You sir, are very lucky.

It's quite hit or miss when (or if) they go bad, but here's the kicker: they're specifically not covered under the powertrain warranty. It's infuriating.
