I own a trans and auto shop and I always require carry out transmissions to be brought back to me for me to check the installation and adjustments.Ģ. I don't know why your transmission builder didn't have you bring the truck to him after you installed it so that he could make the necessary adjustments. You may want to start your own thread.So everyone is focused on your problem.ġ. You should NEVER use a wide 2-4 band on a used reverse input drum, Might want to ask the builder about this. The TV cable needs to be set correctly ONCE & left alone.Its NOT an 'adjustment' for firmer shifts. 472 boost valve, Works well in most applications.

any help would be great (it shifts great manually) and there isnt any dirt in the valve body.

Question 4 ya guys i just got my 700r4 built for my 86 4x4 that has a 375hp 355 small block, the trans has a stage 3 heavy shift kit with a corvette survo case hardened sunshell and gears the works along with 2800 stall converter and a 400 boost valve 8 3/4 heavy clutches and wider kevlar bands as well, now i put it in and hooked it up etc and i cant get good shifts in 1-2 or 2-3 do i gota set my tv cable i called the tranny shop that did iup and rebuilt the trans and they said u gotta set that, i set it to factory by pitting it to w.o.t and adjusting the kick down or (t.v) cable till it was snug which made things atouch better but idk how to properly set it so i got nice firm shifts.
