Any trans experts here?? PLEASE READ!!!!

[Nasty-LSX]

I have a 2006 5.3 4L60e silverado. I burnt up the trans, Got a rebuilt unit 3 year 100.000 mile warranty form a good shop. I removed it and installed it. Super cleaned the trans cooler before install. NO TRASH IN LINES. Got about 500 miles on it and now between 42/58 MPH I get a shudder. If i give it gas it goes away. if I tap the brakes it goes away. That tells me it the TC.
other than that it runs perfect. I called the shop to tell them what happened and he told me to bring it in to get checked on computer. the shudder went away so I did not go to shop. 3 weeks later its coming back. I called today to ask when a good time to come in and he tells me he thinks i have a bad mass air flow sensor and to change it out and see if it goes away. I dont have any problems whatsoever with the engine and it runs like a new truck.

He says thats whats causing the shudder. Is there a way to test this MAFS?
I told him the truck runs perfect and i have no codes. He insist thats the problem.. THANKS

This one works.

but to further his argument. Does it have a new MAF or did you use the old one? Have you tried cleaning it?
If new where is it from?
If used how long was it sitting/ mileage?

You’d think a bad MAF would throw an OBDII code since it’s emissions related...

Do you know for sure tcc unlocks when giving a bit of throttle? It might be just load related instead of tcc

@82Diesel

why me? haha, I don't know anything about 4l60Es.

I was thinking your torque convertor lockup could be causing the issue.
It usually engages around that speed. When you step on the brake it will disengage.

wish i'd seen this sooner. MAF's for that engine (same one I have) start at ~$38 on RockAuto....I'd do that first at that minor of price. Don't tell him the brand cuz he might try to hornswoggle u more.

If anything you'll have a spare to use or troubleshoot with later.
