Trans issue again

[bootlife]

I just replaced my 4L60Eand the new trans feels like its trin to slip. I feel like maybe it's the tune, servo, or converter. It's only at 45 to 65 it feels like the converter in locks and it runs 200 rpm higher. I give it some gas n it goes from 2000 to 2400 be4 it starts gaining speed but its lacking power. Doesn't do it all the time just here and there. Changed converter with trans. Also it's been shifting really hard so I took out the corvette servo but that didn change anything. To day it shifted real soft a few times. When I went from OD to 3rd it was very hard at 40mph. This isn't norm for my truck. Any ideas?

I have noticed that when it feels like its slipping if I Gass on it n make it down shift n let off when it goes back to OD it's norm again

If I was to guess just from what I'm reading I'd say epc solenoid there prone to go out

Not likely unless your tuner really blows. Sounds like its much bigger issues. Who tuned it? Sounds like the trans builder is shoddy or instal is being done poorly.

I was reading on here some where n some1 recommended doing a vette second. What is this mod n how does it help? Also I'm ordering parts to do a rebuild n where can I get it n what I need to make it work?
