1,2 and 3,4 shifts limping trans

[unionmax481]

All just started yesterday 1,2 shift flairs hard then bangs into gear like no other same thing with 3,4 shift eventually putting the trans in limp wondering if this had happens to anyone before I'm thinking it's in the valve body maybe B solenoid. Is hanging up it's a ats stg 5 with co-pilot does it with the co-pilot on or of got about 40,000 ml on trans

What are the codes?

 

[NAFLASH]

Its an ATS trans...

 

[NinjaMax]

Do you have any of the 5 year/500k mile warranty left? I feel for ya, been down the ATS road before.

P0700 I believe was incorrect speed sensor

 

[unionmax481]

Transmission trim resistor, incorrect 2nd gear ratio, B solenoid stuck on- off

 

[Mike L.]

Not much info.

P0700 I believe was incorrect speed sensor

P0700 is simply a generic code meaning the TCM has requested the ECM turn's the MIL on. We need the actual P codes to help you, not just the description.

 

[NAFLASH]

You're going to need a tech2,V2 or an Autocal to read TCM codes.

I have a v2 I kept clearing them last night at the track changing the cals trying to figure out what the truck is doing now I'm trying to get the history of the code to see what they where again

Finally got around to check the code p0776 pressure control B going to pull pan and see if I have a bad solenoid or sick valve or if the filter fell off that's what the gm bulletin is for that code the only thing I can't check is the line pressure

Your clutches are toast. Peel your filter open and you will find clutch material in it. Your C3 clutches will be warped and burned.

Not what I wanted to hear but it happens im planning on pulling the pan tomorrow see what is going on with it thanks Mike

Pulled the pan last night and found that a bolt had fallen out of the valve body and it was the bolt that passes through the main filter port according to my Allison book

Explain main filter port.

 

[unionmax481]

In my Allison hand book there was a diagram for the bolts on the valve body the that was out was bolt 15 that said main filter suction I do believe

 

[unionmax481]

The diagram I have in an Allison hand book shows all the bolt in the valve body and had a description for all the bolts that have a purpose the one for my bolt was number 15 and said main filter suction I think don't hold me to when I get home tonight I'll post a picture of it so you could probably understand me better not very good at explaining things in writing
