2002 L-Series 3.0L Sedan
Default Hard shifts

My dad has a 2000 ls with the v-6 and the auto transmission. Cold, everything is fine. But when the car gets warmed up, it will start to shift really hard. Anyone know what the deal is?

See if it has any codes stored, light on or not. It could be something that isnt too hard, all the way up some decent amount of trans work (PC solenoid).

V-6's with the 4T45E auto tranny have 2 common problems, as mentioned the MAF goes bad resulting in hard shifts and since you mention that it works fine when cold, that's probably it. Other problem is the pressure sylenoid in the tranny goes resulting in hard shifts, but that's usually constant and not affected by engine temps.

Well, it's moot now. My sister was driving, I was riding along, and we got rear-ended at a stop light. The explorer that his us was going about 45, pushed us into the car in front of us. The car is totalled, the tranny is the least of our problems. We weren't injured to badly, the L series is one safe car.
