Can someone tell me what would cause low line pressure after transmission gets warm. I took tranny out to change converter to a ptc NLU from a 9/11 LU. I thought I was blowing thru the converter or maybe slipping in the tranny 2nd and 3rd gear. Was slight burn on 2nd band and 3rd clutches nothing to bad. I put non lock up valve and had tranny guy put new 2nd gear band and 3 gear clutches in. Every thing else looked good. Car shifts fine at low to mid throttle nice firm shifts. At wide open throttle it shifts 1-2 at 5000 rpm then goes right into 3rd.
Line pressures are as follows
Cold
idle 850 rpm Full TV 850 rpm Full TV 1500 rpm
95 115 240
165 115 240
95 115 240

95 115 240
240 115 240
240 115 240
Hot transmission temp 180
idle 850 rpm Full TV 850 rpm Full TV 1500 rpm
100 115 200 - 250 Bouncing
90 115 215
100 125 215
90 100 180

Valve body is a BR3 in a 86 GN.
Could the TV valve be worn ?
