Could someone please take a look at my tables and see if they see anything I'm missing.

At low/mid RPM I'm getting solid shifts.
At WOT my shifts are SLOOOOOOOOW (talking on the order of a ~second) and soft.

I wouldn't be surprised to find my tranny is on its way out, but I'll hope for the best (easy/cheap solution being in the tune).


Reason I didn't post in the tuning section is to ask "whats the symptoms of a dying 4L60E?"

IF it turns out to be the tranny, I might just be putting that spare T56 in my garage to use.

 

anyone?

 

which shift? 1-2..2-3.

actually for either if you put a good servo in it will solve your problem.

 

give me a couple of mins... let me look at that for ya

 

here is your tune with my shift pressures and modifiers.

 

only thing i see odd... is i thought you werent supposed to go below .100 in the desired shift time, i'm probably wrong, but i was always told never to go below .100.

 

1-2 shift is the worst.....2-3 is "better" but still sloppy

I zeroed them out under the idea that I didn't want any delay in the system (bad idea?)

 

I would only zero them out if you have a built trans. Sounds like the band is burnt

 

if you can, just for ***** and giggles, put it back to stock desired shift times for both perf. and normal and just see what happens...

but im w/ built408.. sounds like its something physically wrong with the transmission... i could understand why you think it is not tho. Bc you're probably wondering, well it will shifts fine under light throttle but when i hammer it, it doesnt. But actually it makes sense, that band just might not have the material left to want to grap and hold. You might already have a tranny guy... but i will suggest outlaw here in ga.. they ship and have an ebay page. I think its just outlaw transmissions of cumming, ga that you'd search in google.

 

what about a cracked/bad 1-2 piston?
