My ls400 has 198k, just recently replaced a solenoid because it was skipping 3rd gear entirely. Once in a great while when floored it’ll accelerate fine then when it shifts it slams into the next gear. I’ve tried it when floored on the highway and from a stop.
it doesn’t slip gears at all, if I go slow it’ll shift into every gear smoothly but only when it’s floored.
it doesn’t do it every time but only once in awhile. It’s a pretty hard shift, enough to feel like you’re being kicked..
when I did the transmission fluid change I used the correct fluid from the dealership. The magnets were also pretty clean for the mileage and so was the fluid. (Previous owner kept up on maintenance.
any help is greatly appreciated.
