When was the last time the fuel filter was chg. If you can't remember its time for a new one.If it does not help after you chg. filter, best to fuel pressure test, to see if pump is going bad.

SOURCE: transmission slipping
there are several solonoids inside this transmission .. did he replace all them ? if not I would suggest he do it .. These are problem starters.. they should always be replaced during a rebuild.. thanks jerry

It sounds to me like your transmission is not well. It's working when the fluid is cold but not as it warms up. Pull the dipstick and check your transmission fluid for color and smell. It should be pinkish and smell like oil. My guess is that it will be closer to brown than pink and have a burnt oil smell to it. It the transmission is full, check the level with the trans warm,engine running, in neutral.I'd be shopping for another transmission. If the fluid is below the add mark, you an usually buy yourself some time on the replacement by changing the trans fluid and filter.At the same time add a transmission treatment with the new oil,I've had good luck with Lucas. Hope this helps.

tranny may need overhaul. It is possible that the vacuum actuator is leaking and will need to be replaced. Much cheaper then replacing tranny

Two things: #1 someone has overfilled it by mistake thinking they were putting oil in the engine. Yes I have seen this.
#2 The transmission cooler in the radiator could be leaking antifreeze into the transmission through the cooling line raising the fluid level. I would look for milk shake foam on the dip stick and make sure you check trans in park and not neutral.
