ok i have a 88 chevy k1500 350 with 700r4. well the truck goes through trans left and right, most common is the 3rd to 4th gear change. but the trans i have in it now isn't shifting under pressure like if i were to get it above say 2500rpms it wont shift but if its under 2500 it will shift prefect i have set the kickdown cable numberours times on the trans it does nothing for the problem could there be something else i should be checking.

also is there a site that has pics of how to rebuild a auto trans like ls1howto.com because i would like to learn how to rebuild trans because i have 2 700r4s waiting to be rebuilt that i can take apart and mess with.

 

sounds like it has to much throtle pressure or the goveror is not working

 

Sounds like your Throttle Valve could be stuck in the valve body.

it could also be a sticking governor.
