4L60e line pressure Drive, park or neutral OE pressure should read between 55-190psi. In reverse it should read between 65-325psi. Now these trannies use a pressure control solenoid that uses Amp increments to change transmission line pressure. That being said if you didn't know how the solenoid works. The line pressure will increase with reduced PCS Amps. In drive at idle with your shift kit, line pressure should be reading 70-90psi. Under full throttle in drive you should see 200-230psi. These are the pressures that we see on our transmission dyno and have a lot of good feed back with our customers. You really need to get a gauge on your trans to answer your question. However if the trans has been done 3 times in 4 months you got some issues going on. Good luck.
