Ok I have a 95 chevy k1500 4x4 z71 with a 350 and a 4l60e transmission the transmission doesnt slip but wont shift from 1st to 2nd unless you hold the accelerator at 3000 for a couple of seconds or let off and hit it again
it seams to shift fine into 3rd but i can tell if over drive is kicking in or not
when you hit the kick down gears it just revs up and nothing happons

i have changed both a and b solenoids and the tps sensor i have a bran new computer and the filter i recently put a botle of lycus transmission fluid in and it helps a little i am prity good with cars and trucks but a little nevus when it comes to fixing transmissions aside from replacing them.
i cant relay afford a used transmission rite now

just some thoughts but i keep thinking it could possibly be the valve body or the torque converter the truck has 320000 miles i would realy like to see it make it to atleast 500

im not sure if the transmission is orginal or not but it


Thank you in advance for your time

Pretty old trans but if you think she still good and the electronics are going bad, You may try something pretty neat and cheap...Buy a transgo part# 46-mod... This little kit will able you to convert your trans to shift with a vaccum modulator...Pretty good for a transplant too!

I am having the same problem with my '94 Silverado. Did you find a fix for your problem?

srothery82

I will keep checking around. I miss driving my truck and I'm scared I cause more problems if I don't get it fixed. At least I know it's not the solenoid, that's what I was going to try next.

Oh well, Merry Christmas!

I got information this morning to try taking the valve body off, cleaning it to assure none of the check valves are sticking and reassemble. Do you know of anyone who has tried this? If not, I guess it's worth a shot. I will let you know what happens.
