Where is this located on my 1988 F250 460 C6? How much is it? How hard is it to replace? (can i do it myself). sorry to post a tranny question in here but you get more response in here.

If I remember right it is on the right side of the tranny towards the rear. Like in the area of the right rear corner of the oil pan and up a bit. Look for the vaccume line going to it. One bolt and slide it out. 5 Minute job. I want to say I payed about $35.00 USD for mine but that was about eight years ago.

be careful not to lose the rod that is between the modulator and piston when you pull it out.

hey. while you guys are talking about it, is it in the same spot for a 1988 c-6 auto tranny with the 5.8L? i think mine is going too. it bucks between 2nd a third (hunting) and you have to let up or giver. i was thinking it was the modulator or vacumn line. what do you think? what symptoms are you having?

cheers,

if i mash it from the start it is slow to shift from first to second (doesnt want to shift) and the same when it shifts from second to third. although if i am going like 20 in second gear and mash it it seems to shift down fine (same way if it shifts from third to second)
