Allison 6sp: TransGo Jr. installed now giving me P0972 code

[ruffmanatv]

Talked to Mike today and he said it was a wire not connected, but I just had the pan off and check all the wires Twice. Silinodes are all in the correct locations. Code throws trans into 3 gear and will not let it shift from there. Any Ideas? In need of desperate help.

check and make sure that the main harness is plugged in all the way. as well as glance at the wires on the inside of the pan from the plug. i would disconnect the plug and make sure none of the pins are bent or covered in dirt or something

You left the one above the trim solenoids unplugged.

not sure if this will help but I know a guy who didnt fill the fluid up all the way in it was setting codes

go back and double check all harnesses like everyone else said. make sure they are all snapped in. sometimes when you have been staring too long stuff escapes you. when im like this i work backwards to look at everything differently. usually catch it that way

Does your Hypertech reset codes? Just wandering cuz i know nothing about the max energy.

Like was said go thru and re check your connections. I had my pan off twice when i did my JR kit. And theres not a lot of room around the wiring.

you'll get it!!:hug:

Ok. Well I think I found it, but not sure. The solinode above the trim valve solinodes is cracked where it plugs in. I am going to take the valve body back out and replace this solinode.

Any idea where to pick one of these up?

Replaced shift solinode C today. Local Allison dealer had two in stock, Thank God. No more codes now.

Only question I have now for someone who had this, Is it normal for it to slip a bit between the 2-3 and 3-4 shifts and also the 5-6 shifts until it relearns?

you mean slip like the trans limps or kind of flares?

I suppose flares. It just kind of goes out of gear and then slips and pops into the next gear.

Take it easy on it if it's shifting funny. Can you find anyone to reset the taps?

I am going to call someone tomorrow. I will just have to baby it a bit until it relearns I guess.

Did you ever get this sorted out?

So did you just baby it or did you reset the taps?
