Ok had my 80e built by a local guy suppose to have an hd2 kit in it but the 1-2 shift has a delay and then slams into gear instead of a crisp 1-2 shift like my 60e had it like drags out then hits I've played with pressures and shif times in the tune but it doesn't help any suggestions?

 

My 80e shiftes nigth and day quicker. did you check fluid level? Is it only WOT or it this all shifts? If its only WOT my guess is its low on fluid.

 

I have checked fluid level. It does it at part throttle to. Normal light throttle it's fine but soft, And the 2-3 and 3-4 shifts are fine and it locks up like it's supposed to.

 

Did you ask the local guy who built it?

 

Yea he tried telling me it was fine that the motor felt like it was falling on its face I've got the feeling I'm about to get the run around I'm gonna go back he's suppose to scan it but even if I command it to shift at 6000 it will do it right now it's commanded at 6600

 

What's done to the motor?

 

Who tuned it? Post up the tune if you can.

 

It's a 5.3 with ported milled 317s and a tick sns stage 3,tbss intake 90mm throttle body made 394whp at 6400 I'll post the tune when I get my laptop I played with the tune had as much line pressure I could get and 0 shift time same thing added a little shift ti.e so it was .150 same thing

 

Trans itself has issues just started doing some weird crap in 3rd gear now slip grab slip grab slip grab he's gonna have to try again maybe he'll rebuild it correctly the 2nd time

 

You need to get a pressure gauge on it.
