Bit long winded, may want to get something to drink.
Bought the truck in 07. Grenaded the trans. Friend owns a shop, his builder went thru it replacing anything that was questionable. Only thing that was factory was the convertor...which I broke. Got a TCS triple disc billet convertor. Left the desert and moved to the Inland Northwest.
For several years now when the ambient temperature is below freezing I have 2 choices...let the truck warm up until the trans temp is above 35 or get a very harsh first shift. Every time I went to see my friend fixing it just never happened. He would dump the fluid, replace the filters and then remember about the slam shift. The builder my buddy had the last time I was there told me that when he owned a shop in Oregon he seen quite a few early trucks with sticky valve body valves.
Fast forward a bit and the truck started acting a bit weird when taking off from a stop. Felt like you had a trailer behind you with the electric brakes cranked up.
This past summer I made several trips from the Spokane area to Yakima, I am the track camera guy at Renegade. Noticed that my Edge display had the trans temp over 230*...it never ran that hot even pulling 12k pounds thru the desert. Hit the trans sump with a touchless thermometer, it read 155*. Buddy said I needed to replace the pressure switch. Did so. And hell broke loose. P0700 and P0875. Replaced the NSBU. Checked all the grounds. Checked damn near every wire I found on the schematic that is trans related. All is good.
Truck has been done for 3 weeks now. Have 3 trips remaining on my camera gig. I am disabled, renting a car is putting a hurting on the bank. Need to get this thing up and running.
Buddy suggested I drop the pan again. Pull the valve body and check the valves to make sure they are moving freely. He also told me that he had picked me up a set of TransGo Valves. He blew his trans up a while back and they went into his trans prior to him selling the truck. He told me that these valves being a bit sticky could be causing the cold issues as well.
Any thought/suggestions/comments would be greatly appreciated.
