Codes 1832, 1823, and 1783 for transmission . I've looked them up and they're all for circuit failures or malfunctions so now I don't know what is the right path to take rebuild or fix those failures if it's possible. I've replaced all plugs and coils pretty easy thought it would be more difficult with the location of last 2 plugs next to firewall. Also the abs/wheel speed sensors on rear axle and front wheels that wasn't very fun they didn't want to come but I'm patient and love my truck so got them out no breakage. Plus the OSS sensor on transmission taking it to different shop tomorrow to see if it fixed any of the other issues. Any help would be great also she runs great till upto temp then will slip in D when taking off from a stop occasionally. Thanks again

 

Truck details, please?

I'm betting your 4wd doesn't work? Looks to me like you have some electrical issues, plus with 306k it's probably time for a rebuild. I'm also betting the fluid is dark and burnt.

 

I've never needed to use my 4 wheel drive so not sure if it ever worked. Yes the fluid was pretty dark and had a bit of a burnt smell to it not really any pieces of metal in it but still had the sludgy stuff that kinda accumulates at the bottom of the pan and the shop that replaced my timing chain didn't put the magnet back in it either. The Trans is the original from what I know about the truck my cousin had it before me since 2003 and he said he didn't replace it. The motor is super strong and sounds really good still drives good too till warmed up. I definitely don't want to get rid of my truck so hopefully there's not electrical issues too. Thanks for the input greatly appreciated.
