Jonathan, I cannot call. I can text. About the vehicle, did you happen to scan the vehicle to get the transmission codes?

Not yet
Automotive Expert
Ok, in order to help you get to the bottom of your shifting issue, I will need those codes.

I have a konra ELM 327.Will the transmission codes come up under a check [engine](/topics-engine-chevy/) light or is it two different things
Automotive Expert
There may be a P0700 in the ECM, but that only indicates there are codes stored in the transmission module. I don't know if that reader will pull transmission codes.

I don't think it will but I can try
Automotive Expert
The code reader I use is a bLUEDRIVER.

Ok ill look it up
Automotive Expert
Sounds good. When you get a code, please reply here and we can continue this chat.

Here's a screen shot of the codes it pulled

What is the condition of the transmission fluid? Did you change it or the spin on filter recently?

The last time it was serviced I took it to a transmission shop that was two years ago I think and I have touched it.The fluid still looks good like its new
Automotive Expert
Ok, If the transfer case is clean and working then this may be a sticking valve in the valve body.

I just remembered that over the summer they put in the new bell housing I believe or something to do with the Allison's that year
Automotive Expert
Ok, here is a quick check. See if there is a magnet on the top of the spin on filter. If not then for sure you need to clean the valve body and install a magnet on that .

How do I do that? Just drain the fluid and spin the filter off and check or something else?
Automotive Expert
Just spin it off. You won't loose hardly any fluid, couple oz at most. If there is no filter on top or around the threads, put one on. But then it will need the valve body removed and cleaned. that magnet prevents smaller metal particles from getting back into the valve body and plugging it up .

If there is a magnet what else could it be?
Automotive Expert
There is a small one in the pan, but there MUST be one on the top of that filter!!

Thats what I mean if the magnet is on top of the filter
Automotive Expert
IF the magnet is still there, I would still clean the valve body and look for debris of any kind in the transmission.

Ok is that something I could do in my garage?
Automotive Expert
YEs, there are no gaskets to replace, the torque on the valve body is 106 in lbs in a pattern from the inside out. Remove it, split it and clean it, use a wooden dowel or something to make sure each of the valves move.

Ok I will try that I was going to send to the shop tomorrow but I will try that first
Automotive Expert
Ok. Sounds good.
