I understand this might be bit off topic but I'm sure you guys might have some suggestions. My brother owns a 2000 3.0l v-6 lincoln ls and he's having a problem with revolutions. It redlines at about 6000 and when he gets on the freeway trying to accelerate to a cruising speed of about 70 he has problems. I'm not sure if he's got four or five gears but it seems like he can't get it to go into the last gear. When he hits about 50mph and accelerating more not hard just easy acceleration rpms jump from 2500 to 4500 like it dropped a gear yet there is not pull in power. It also heats up sometimes. Something is f***ed up.
Best we can come up with was the transmission. We tried changing the tranny oil but it's got no dipstick in top of engine bay. The manual says to take it to authorized mechanics. Someone else said it was needing hydraulic fluid for the engine fan. My brother checked that out and said levels were low so he added that and it hasn't heated since.There's all kinds of lights like check engine
and other lights I don't know what they mean on the dashboard. Anything would help.
