sound like the common shift flare issue. Does it feel like the trans is slipping from 2nd to 3rd? if so it's most likely a blown valve body gasket

1st to second does it and 2nd to third is really bad but the weird thing is sometimes it doesnt downshift? ever heard of that happening as well ?

alright im looking into a valve body gasket but i also want to do a shift kit? and good barnds i should look into??

 

[Rose2300]

I've heard transgo is a good brand, and they're inexpensive

alright so i did the valve body gasket it tool care if the second to third gear issues but first to second is still acting up i was going to look into new solonides anyone else got any ideas??

 

[Rose2300]

Could be the epc solenoid. maybe the bands are wearing out?
