Few weeks ago I popped a trans cooling line in my 2008 lexus isf, after doing a radiator swap. My bad!.. Thankfully I was at a stop light! I immediately shut the car off and get it towed to the stealer ship. They popped the drain plug and and said it was bone dry. So I leave it there over night, Get a call the next day and they say its its filled and drives perfect. Low and behold it does. Next day I wake up and start my car and let it warm up for 20 mins befor i head to work as I always do. back down the drive way and pull out put it in drive and as it shift from second to 3rd i feel it slip. So i do some research find out the fluid levels could be wrong and that the transmission isnt building enough pressure to shift right. So befor I pull out the next morning I hold it in reverse for a about 1 min, then back down and as I drive off it shifts perfectly in to every gear. The next few times I do not replicate this and it slips! Every time. but then drives fine the rest of the day.. If I hold it in gear befor I drive off the pressure builds up and it shift perfect right off the bat. now I call Kuni lexus of Portland and they say this is a sealed unit and there is no procedure to do fluid level check.. I know this is bull **** cause other sealed units have a procedure to check fluid level. Can some one pointed me in the right direction
