Attention: TDR Forum Junkies Hi and thank you for reading - and any insight!
I have a 96 CTD 4x4 with the 47RE - no modifications or anything truck has~150K trans replaced with factory rebuild at ~120K. Here are all the stupid things I did and what happened:
Decided to change fluid and filter just before driving across the country.
Adjusted bands to spec on fritz ram tech page.
At the same time I pulled the drive-shaft to have new (grease-able) u-joints installed.
Therefore I had the transfer case in Neutral when all was done.
I had also adjusted the shift linkage slightly.
Sooo... I went to shift the transmission around a bit to get the fluid going and top up and, as you can imagine, I heard the parking pawl complain loudly. I must have shifted in and out of park 2-3 times (thinking I may have adjust the linkage poorly) before realizing I had the transfer case in Neutral. Well I know that's not too bright, so no need to let me know.
On my test drive the trans started by shifting fine but after a couple of miles the 1-2 shift especially started to feel wrong. Nothing extreme but I would describe the 1-2 and 2-3 shifts as follows:
From a stop 1-2 shifts VERY soon and feels as if you hit the brake slightly then grabs a bit hard. 2-3 pretty much the same feeling: slight loss of torque then slightly jolting engagement.
Well that was in California, it didn't feel too bad so I assumed my torque wrench was a bit off and backed of the front band ~1/8th of a turn.
During the drive it really started bothering me - by my reading the bands were probably fighting each other for a moment before shifting.
So in Cheyenne Wyoming I found a transmission shop. The owner test drove the truck, did not think it was too bad, but agreed that it would be good "peace of mind" to pull the pan and readjust.
Well he did things by "feel" so all he ended up adjusting was the front band (backed out one full turn). He did not think ATF +4 was worth the money so he refilled the trans with Dex3 and some additive "Lube guard. " He also found some aluminum in the pan. That was NOT there when I changed the fluid and filter. He also gave me a sheet with band adjustment specs that were very different from those that I had used.
After that it shifted HORRIBLY - same symptoms times 5 - very jerky shifting.
When I got to NY state I dropped the pan, adjusted the bands to spec, filled with ATF+4 and test drove - better, but not much better than when I left CA. I drained and refilled the fluid one more time in case the Dex3 was giving me problems. Still about the same.
My current theory is that my bands were never the problem and that when I shifted the trans with the transfer case in N I sent some chunks into the wrong place. But where? I Have read about the governor solenoid - but nothing with my same symptoms. I am sorry this is so long but please let me know if you have any insight on what is going on. Automatic transmissions are like voodoo to me! Thank you very much!
