It has 107,000 miles on it At more than 1/4 throttle it wont shift 1-2 occasionally wont shift at all unless thrown into neutral then back into drive. I've had a transmission flush done screen replaced aswell, I've replaced the pressure governor cel light was triggered by it. Shifts smoothly when it does and in every other gear

 

any codes now ?

 

Still no codes. Realised front band anchor dropped just finished putting it back up and adjusting it but still no improvement possibly worse somehow.

 

Have the sensors all been replaced ,shift,solonoid,speed,etc?
I adjusted rear bands on mine but i know it must be just right on turns.

 

Pressure governor has been replaced but other sensors have not.

 

Ive heard its best to replace em all when your servicing the other sensors there

.Even some kits put all the sensors in them like in 1st pic .
I replaced broken spring in mine along with another overdrive .I cleaned up the speed sensor of the fine metal particles while under there too.

 

At this point im debating If replacing the rest of sensors are worth it, or just replacing the transmission and being done with it. Local transmission shop that did the flush said there was possible internal damage and excessive debris in pan. I've put to much money into this truck to justify giving up on it.

 

Those effect when it shifts for sure.Try some used ones to see if it stops .Band adjust too.
Jerks at tranny ahop said id need a rebuld.. BS i put another overdrive in an replaced that broken spring an changed shift sensors..going on over 3000 miles now.

What debris was in the pan?

 

I'm not sure how much of what was in the pan when they did the flush when I've had the pan down myself I've seen some light metal shavings and some light clutch material. Good idea I'll try to find some used and see if they make a difference.

 

Update: after sitting overnight transmission fluid wasnt reading on dipstick added 3 more quarts checking level occasionally took for a test drive and everything is smooth so far will be checking fluid again tommorow no signs of any leaking guess it hadn't fully settled when i checked it after putting 4 quarts in after putting valve body back up
