auto tranny problem..
hey i got a problem.. when you put the sc300 in drive and no matter how hard you hit it 1st gear feels weak or maybe feels like a slip. but either way it feels abnormal.. when you hit the gas under any throttle 1st gear whines out to redline then shifts to 2nd. 2nd engages but the rom increases but does not move car or accelrates.. 2nd gear does engine brake so its weird.. 3rd gear and o/d is working fine. its mostly 2nd gear im worried about.. i did a stall test specs say 2200rpm give or take 150rpm.. at idle with the pressure test hooked up it reads 55psi in specs.. at stall speed it reads 130.. which is under specs (189+ specs).... in reverse in idle it read 75psi which is under specs and stall speed in reverse is 215 under specs (should read close to 250+) i herd about some kind of vts or somehtign about pressure control valve but idk im new to the auto tranny but learning. any one can help me? history..... i gotten a code 63 2nd selenoid was malifunction.. so i replaced it. with a napa brand not oem.. but it worked fine. what happen was it would strat off in 1st gear but skip to 3rd.. but you could manualy down shift to 2nd gear and it would fine... any way the selenoid got replaced and it ran good for 2weeks until 2nd gear acted up..
