This car is an auto trans.( my bad,I did type manual,sorry for the confusion) By shifting, he's saying that he takes off from a stopped position, and as he is driving the car will go, and after you reach say, 25mph, the rpm's are up to 3000 and then back normal, it feels like it's trying to go to the next gear, but he can't really drive much above 35/40 mph....by shifting that's in relation to the rpms...it feels like it needs to shift but doesn't, I don't know if I'm explaining that exactly right. I guess like it's holding back, can't go really very fast, and I'm guessing that that's because of the sensors needing to be replaced??
That's awesome news...thank you thank you...you have been extremely helpful...I mean it!!
