It's there...thank you so much. The fact that TS keeps crashing every time I try to change the Dropdown menu on Powertrain / Hybrid Control / Data List / Primary..... means I couldn't even get to the T/M Oil Temperature choice....but i did manage to use the TAB key to get to the ALL DATA choice and all the transmission data is in there.... so have my trans temp and Line Pressure Off verification now...can get that last job done this weekend. Thanks again for the assistance. Much appreciated!

This one has me stumped......... I changed the ATF in my old Gen 3 GS450H last year (2008 2GRFSE) with no problems. Followed the Lexus Tech document and drained refilled 3 times and was able to get transmission fluid temperature and line Pressure status in Techstream and closed up the plug at 35 degrees and job done. bit messy...but otherwise easy. I bought a Gen 4 GS450H (2GRFXE 2013) a few months ago and have been doing the usual maintenance every weekend. Down to the last job now which is transmission/E-CVT fluid. Same process as my Gen 3 but this time there is no mention of Transmission temperature/status/line pressure/ anything related to transmission in Techstream. I have tried Techstream V12 and V16. I have tried Torque Pro and ELM327 bluettoth OBDII on my phone but no mention of transmission related data there either. Am starting to think something must be crook on my AT ECU but Techstream gives no error codes for anything on a HealthCheck. Am about to give up and just drain at room temperature and refill with exactly the same amount....do this 3 or 4 times and I might have semi-decent newish fluid!! Any ideas anybody?? Thanks.
