the other day i was drivin my truck and it seemed like when it went to shift it would jump up about 500 RPM's before it shifted into the next gear...once in gear it drove ok...i was driving it the other night and comin up a steep hill and i started hearin a thumpin noise and viberation through the floorboard....now between 1500 and 2500 it likes to rev up.....what do yall think?

 

sounds like its time for a rebuild......its probably a combo of both tranny a nd convertor

 

thats what i was afraid of......this truck is gettin expensive...200 last week now this

 

Converter is probably fine...you probably lost your 3-4 clutch pack and your band.

 

Which would result in AT LEAST a convertor drain and cleaning but most places are going to push a new convertor (probably a hd version)

 

would i be better off gettin a new converter or would it prolly be ok to just drain and clean this one? i dont wanna spend any more than absolutely necessary right now...moneys kinna tight

 

I would spring for a new one and get the HD version if you can. not replacing the TC would be like cleaning a fuel filter intead of replacing it. if you do just clean this one I would have it checked out first but convertors are not that expensive it would be well worth the investment then it all has a warrenty. some tranny manufacturers will not warrenty a tranny unless you replace the convertor also.

 

There are guys running twice the hp you make through stock converters with no issues. So if it were me, I would do a flush since you said money is tight and you only want to do what is absolutely necessary. My two cents.
