It’s the most important thing to do if you want a trans to last- check the fluid level regularly. Performabuilt told me it’s the cause of most failures with a 4l60. And nobody will warranty it if it fails. Even 1 quart low on a 4l60 will shorten its life considerably.

So I finally made it out and took a picture of how my parking brake cable is routed after leaving the firewall. Is this the norm for anyone with this year/body style?

Ooohh i see. Yeah it does. I don’t think the new one will come with the new one is going to come with the vette servo. I will be doing that upgrade for sure. $22 and it makes a good bit of difference. I’m going to take the mechanic some doughnuts and $20 tip and see if he’ll pull the one out of the old one to put in the new one. Its external, and takes 20 min. Probably 5 if you have it out of the vehicle.
i see that. :/ i’m going to be better about it for sure. And annual fluid and filter changes
Performabuilt told me a quart over is not a problem and if it’s too full it will go out the vent anyway, better a quart over instead of a quart under.

i have heard that going a little over is also good if you like to corner hard.
like if you start sucking air when driving spirited, add a little extra to prevent it.

I run a quart over and my driving is definitely spirited lol.

got my garage nearly ready for the ol hoe.
been slowly looking at parts.
any reason to not run the melling high volume high pressure pump?
looks like it has a better finish, and comes with the stock pressure spring...

per my father-in-law i drive like i'm on a race track.
I just tell him i like to feel the G's
And i drive my vette like i stole it most of the time.
my tires don't last long...
I just realized the airbag cover i ordered is GMC not Denali, o'well maybe I will put on there anyway someday when I swap in the new steering wheel
ditto, except the vette part, lol someday when these little minions are out of the houseper my father-in-law i drive like i'm on a race track.

Six of one half a dozen of the other. Either way is fine.

I have the Melling HV/HP pump with the HP spring in it... no real issues other than the ECU thought the pressure was TOO high so I had to recalibrate the sensors output with a resistor so it reads lower on the gauge.

How long has it been in? 2 yrs? No other issues with it? Will you be able to tell if you have a low op situation, even with the resistor in place?

It has been in for 70-75k miles, probably 4 years, I believe.
Yes the gauge is still fully functional it just reads about 15-20 psi lower on the gauge than it actually is at the engine. But if pressure drops or rises, so does the gauge... its not just a static reading.

I Just got the low down on these high volume pumps. If anyone else is curious:

It’s actually been a couple days, but putting some finishing touches on the front end:
Smoked the fog lights. Dipped the logo and the chrome piece on the hood (dang it takes a long time to spray that peelable rubber on...6 coats and you have to wait 15 minutes between coats). Wife doesn’t like it and the kiddo says it’s okay. I’m digging’ it though.

Not my thing, but it’s cool if you like it.
Melling has some great information as well. That article by Summit isn’t really helpful for guys trying to correct an oil situation in a worn engine. Here’s a quick explanation on pressure vs flow that puts it in an easy to understand comparison. Melling has some videos and other articles that can help a person to decide on an oil pump. https://www.melling.com/wp-content/uploads/2017/03/pressure-vs-flow.pdf

Good article there. Explains it well. Thanks!
