Hey guys needing help all mechanics around me are full for a week + any advice welcome.
Ok so my new to me 05 t4r v6 4x4 had an intermittent battery light comes and goes as it pleases(I cant catch it on long enough to check put what's the issue) so fast forward I get a oil changed (could be unrelated but I put it in just in case) It threw CEL with the other VTC off and the code was for stuck open thermostat (replaced with the aftermarket one the auto parts had in stock) so everything was good. Go camping and on the way I notice that when trying to preserve the petal to accelerate I get no power or response. Then it would and seemed to switch gears fine. Noticed I cant get into o/d. Massive power loss going up an incline which I live in wnc its inevitable. So going up a mountain now I use 3500 rpms just to barely make it to the top of my road steep incline. I heard a loud whine or air sucking maybe? Anyways it goes ok on flatter land but any extra need off power its grasping. I got a code for p2714 and then next day was a p0776 the solenoids in the trans.... but I was counting and it seemed to switch ok I tried using the 1234 selector to try and go up in low gear but not really any difference. Please help I dont want to throw money in it if it's something big but i do want to fix if I can. I just paid waaay to much for this car for it to be having problems like this. Unfortunately were on our own here and are savvy DIY sellers. I've been researching for days and I have a huge list of could best and maybe but can anyone maybe help me where to start checking or ruling out most likely first. We do have a multimeter if you've read this far a thousand thanks yous. Any help advice appreciated
