and again.... ignoring this won't make it go away. lol
2014 Silverado 5.3 - New Mod Template
I couldnt ever find anything on this but Jakes performance sells an adapter for like 150$ that will make your trans full manual! I got rid of the 4L80E and put a Th400 in mine with a full manual....
LQ4 408, Pt-88, FIC 80# Injectors, 4l80e Stage 2, 2002 Gm Computer 3Bar Sd, 3.42 Gears, 30" Tire
Some 4L80E tunes have the WOT upshift & downshift speed tables when in manual 1st, 2nd and 3rd. Yet others that I've looked at, don't.
I'm sure that support could add the tables to your OS.

I forgot about this thread, sorry. The tables were added on my OS but they didn't work so I ended up doing a segment swap back to a 60e tune and it works fine now.
2012 Cruze 1.4T, mods to come.....
1994 Chev Work Truck 6 liter with PT76GTS/4L80e
1993 S10 Blazer AWD 6 liter with LS3 heads/4L80e
I know this is old but how is there a way to test this without blowing up the transmission if the trans brake engages while moving?
Did anyone ever get this to work? I am tired of my 4L80E shifting out of 1st on its own. It's a real pain in the ass when trying to go from a dig, your tires spin so you get out of it a bit, then all the sudden you are in 2nd gear. A fix for this would be great.

2002 Avalanche - Stock
Add another one to the list who's having this issue. Quite annoying for the reasons already stated. My ECU is from a 2003 Silverado 2500HD. Any updates on this?
No I bought hptuners because I heard it had good support but I'm not seeing it...thinking I should have gone with "the other brand"
I'd just like to be able go use my trans brake without the chance of blowing it up. As Russ K stated my OS is one that doesn't have the WOT shift table...which is the only time I will be using my trans brake
I sent Chris my OS ID but he got back to me and said he doesn't see any WOT shift tables for that OS
Still haven't heard anything back
Russ K was talking about some WOT tables which I don't have. My tables are "256'd" out...I'll try to get some logs soon but I'm not sure you understand that if my trans does shift into 2nd while my shifter is in D1 my transbrake will engage at whatever speed I am going and cause damage to my transmission

Thanks for the update Bluecat, lots of rock crawlers out there waiting to be able to hold 1st!
