The day after I posted this the "Service Engine Soon" light came on. Went to Autozone and they hooked up their OBD II diagonostic computer which found trouble code "P0751" - "1-2 shift solenoid stuck off" or "1-2 shift solenoid circuit fault".
The rep told me that altho they don't sell auto trans parts like this one, he knew of a transmission supply company in Raleigh that would have one. He gave me their address & phone #.
Skeptical that I could repair this on my own, I called them up and asked if they had one for my tranny and he said yes. I then asked how difficult it was to replace and he said it was no big deal - "Come on over and I'll tell you what's involved".
Got over there and the solenoid was on $12 - $13. He said to drop the drain pan, pull the filter, and showed me which solenoid was the one to replace. (The 1-2 shift solenoid is identical to the 3-4 shift solenoid.)
Went ahead and bought a new filter, pan gasket, and trans fluid while I was there. Total cost - about $75.00 including a repair manual. Went home and pulled the pan. Sure enough, a disassembly of the solenoid revealed a tiny piece of metal that prevented the check valve ball from seating properly, which allowed fluid to continue to flow thru the solenoid-activated valve when it tried to shut off.
I installed the new solenoid, trans filter and gasket, refilled it with fluid, and presto! Works like a charm!
I saved myself approx. $300 - $400 a trans shop would have charged. And you know they would have tried to talk me into add'l charges for a complete overhaul with the line "We won't warranty anything we do to it w/o doing a complete rebuild" even though the truck only has 48,000 miles.
Fixed it myself - and lovin' it :D
