I drove a donor 1997 ford explorer into my shop and used an and advance adapter 50-2704a conversion kit to mate the awd 4r70w up to the dana 20 transfer case. All locks when engaged to the driveshafts. I used the original computer and required the harness, etc. engine seems to run as expected.
Here’s the issue. I have no movement in any gear. Little to no fluid flow to the cooler. When I put it in gear, the rpm’s go up 2-300 rpm’s for a given period and settle (I would typically except it to bog down because of a load to move).
What I did initially to check was I took the pan off to see if the new filter had fallen out. It was in place, and I did get the old o ring out and install the new one. I took the trans back out to check to see if the TC was fully seated and to inspect the pump for any damage, cracks, or leaking. All was perfect but I didn’t remove it and look beyond the surface. All I’ve done to the transmission outside of the conversion kit (didn’t disassemble the trans) is drain the trans (not the tc) and put in the new filter. I do remember defaulting to manual transmission ways and I filled initially through the line port and not tho dipstick tube. I am used to manual transmissions and automatics are somewhat foreign. However, when I checked the pan, I did get all the fluid out. So I don’t think that caused any issue.
I am trying to figure out why I have no fluid flow to the trans cooler. Everyone I’ve talked to has said that it has to be the pump because it’s mechanical. I was thinking at first it could be a valve body/solenoid issue of some kind, but am unsure as I don’t know automatics. I began taking things back apart but stopped and thought I would ask here and perhaps Clinebarger or someone with more knowledge here can provide some insight. The rpm increase and no movement has me puzzled even though I understand if there’s no flow… there can’t be movement. Just as a side note, everything went in well, there was no whines, grinding, or noises abnormal when running, and I’ve seen no shavings at all in what fluid has come out.
