Hey guys, I did a search but cant see anything exactly like my issue.
05 Vz alloytec 175 with 4 speed auto, 255,000k's. runs perfectly normally, with no oil leaks or issues etc.
Driving on the freeway a couple of weeks ago the gearbox felt like it slipped into overdrive, and then wont kick down gears. It feels like its lost 80% of its power even with the throttle all the way flat to the boards the speed continues to fall slowly like the brakes are on and the engine is kind of labouring. To fix it I just take my foot all the way off the gas for a split second, then back on and everything works perfectly again. Has been doing this on and off for these past couple of weeks, usually 2 or 3 times during a 40 minute freeway run at 110k/ph.
Im thinking throttle position sensor at a guess, but Im not really up on all these electrical/sensor type issues. Any advice would be great.
