Tranny problems

Having trouble finding this exact issue by searching so posting up to ask.

My dad has an 05 4x4 v6, just serviced the tranny, drove fine for a while (10-15 miles), but stopped at a store an tried to start off again and the transmission does not want to work in 1st gear. It seems to "catch", not creep forward like slipping, but actually jump forward if he revs it quite a bit, but won't shift into a higher gear and continues to move forward in first.

Reverse works 100 percent fine, that's the difference between what's going on and the majority of threads I can find.

I don't really know anything about automatics, or how they really even work, and know even less about 2nd gens in general, so really hoping TW can come through with some suggestions.

 

Ah just realized i posted this in the classifieds... Can anyone tag a mod to move it?

 

What does serviced the trans mean? Fluid level might be low

 

New filter, new pan gasket, drain and fill, watched a quick video on how to do the service and cracked the overflow plug open and fluid is there, is there a different process for a full flush?

 

Sounds about right. After you filled it up, did you start the engine and shift through all the gears with a short pause in between each shift?

 

How many miles are on it?

 

I'll have to ask him, is that some kind of a process for filling oil passages or something?

Recheck fluid level. Unlike engine oil, tranny level must be checked while running and there is a temp range where it should be. Link has the info.

 

That title thoooo

 

Glad it’s not just me
