have you tried the governor pressure solenoid? If not look into that. I was talkin to a guy on here and his tranny was fallen out of second also and huntn in between gears. He replaced the governor pressure solenoid and transducer and adjusted the bands and all is great now! GoodLuck! Search the posts for (Updated Borg Warner Governor pressure solenoid)

Adjust the band it solves the problem. its required every 33,000 miles. Line pressure can be raised but pan must come off. counter clockwise 1 turn= + 3psi.

My 48RE slips also in 2nd. The famous 1-2-1-2 hunting! She has 150k miles on her tho. Stock.

Im looking into doing the Manual trans swap for mine. But I'd prefer swapping a trans into my truck than buying another truck with a 6spd in it already.

I just have to find the materials. Meanwhile im killing the tranny driving Standard-like. Heh. Poor her.

04.5 CTD QCSB 4x4 Swapped 6spd, 6" BDS, 37" Mud Grapplers, Smarty, AFE Stage 2. SOLD
98 12v ECLB 4x4 5spd, 5" exhaust, that's it.

It's because ur TC is draining off while it sets over night , they have a valve u can put in ur valve body so ur tranny will pump fluid n park and not do that . I would recommend not revving it till it gooes either I would shift it to neutral n let it idle for 10 secs to pump the fluid threw then put it in park and go

My 06 did the same exact thing at 90K miles. I bought a transgo shift kit, new transducer and solenoid and then dropped the pan. Pulled the valve body and put in the new stuff. Adjusted both bands (one internal and one external) and it's been like new ever since. I now have 181K miles on it.

You will need an INCH LBS torque wrench. there are directions all over this site for how to adjust your bands. Very simple.

Shift kit is intimidating to install but is NOT hard. You will need about 12 quarts of ATF+4 to refill. I also did a flush before I dropped the pan and then used a little of this in the oil at refill. Works like a champ.
