99 club cab, 3.9, 42 RE (I assume. may be 44 RE, definitely NOT a 46) getting a little slippage in 2nd especially when stone cold then it goes away and shifts fine. gonna try to adjust the bands. how many turns do I back off after I torque them to the 72 in/lbs? fluid still clean, not burnt yet so I'm hoping just an adjustment might fix it.... otherwise works/shifts fine. 1-3-OD,R are all just fine.

 

Need to verify which trans you actually have, as I think the specs can differ widely between them.

 

Only difference between the two can't really be seen unless trans is taken apart. The only thing that is different is the number of discs in each clutch pack otherwise identical between them. I'm not taking it apart to tell that just so I can make a simple adjustment.

 

42RE:
Front:
(3) Tighten band adjusting screw to 8 N·m (72 in. lbs.) torque with Inch Pound Torque Wrench C-3380-A, a 3-in. extension and appropriate TorxTM socket.
CAUTION: If Adapter C-3705 is needed to reach the adjusting screw, tighten the screw to only 5 N·m (47-50 in. lbs.) torque.
(4) Back off front band adjusting screw 3 turns.
(5) Hold adjuster screw in position and tighten locknut to 41 N·m (30 ft. lbs.) torque.
Rear:
(4) Tighten adjusting screw to 8 N·m (72 in. lbs.) torque.
(5) Back off adjusting screw 4 turns.
(6) Hold adjusting screw in place and tighten lock- nut to 34 N·m (25 ft. lbs.) torque.

46RE:
Front:
(3) Tighten band adjusting screw to 8 N·m (72 in. lbs.) torque with Inch Pound Torque Wrench C-3380-A, a 3-in. extension and an appropriate TorxTM socket.
CAUTION: If Adapter C-3705 is needed to reach the adjusting screw, tighten the screw to only 5 N·m (47-50 in. lbs.) torque.
(4) Back off front band adjusting screw 2-7/8 turns.
(5) Hold adjuster screw in position and tighten locknut to 41 N·m (30 ft. lbs.) torque.
Rear:
(4) Tighten adjusting screw to 8 N·m (72 in. lbs.) torque (Fig. 73).
(5) Back off adjusting screw 2 turns.
(6) Hold adjusting screw in place and tighten lock-nut to 34 N·m (25 ft. lbs.) torque.

 

ok thanks.... I know THIS truck that needs the adjustments, is either a 42 or a 44 RE..... (not sure which though)
but my '96 4wd is the 46RE.... I'm ~98% sure that if the 99 is a 44 instead of a 42, that it would be the same as what's listed for the 42....... the "turns out" from torqued, is way more than I thought it would be, in either case.... I was thinking ~2-1/2 turns out.

 

My book doesn't list the 44RE since the 5.2 wasn't offered in 2001, having been replaced by the 4.7. But I think it uses the 42RE case.

3.9 = 42re
5.2 = 44re
5.9 = 46re

47re and 48re are for the V10 truck engine and cummins.

 

42 and 44 are both the "smaller" series of trans, the 46,47 and 48 are all the heavier transmissions, biggest difference among them is numbers of clutch discs within the clutch packs. A 44 is slightly stronger than a 42, and of the larger trans, the 47 is just an upgraded 46 inside, the 48 is a little beefier inside than the 47. But side by side within each series they look identical to each other.

I have to go inside my 42, band adjustment didn't help. Just got a new front band today, have Sonnax upgrades coming for everything that I can get. Only going as far as the front band, and valve body. All other function is too good to mess with.im glad I have my own lift at home, I'm gettin too old to do trannies on my back any more. I've done more of them that way over the years than I can remember.

 

If you look at the transmission pan, If the pan is square and no humps then its a 42/44 re or rh it the pan has a hump on a corner, Then its a 46re or rh

 

Take it from me. Don't use the band adjustment specs. What want to do is loosing the retaining nut on the front band which is you kick down band, adjust the band until you have 1/4 to 1/2 of free play. Do the same on the reverse band too. And make sure you tighten the retaining nuts.

 

thanks. I've worked on and owned enough Dodge's to be able to tell that much. And how to tell the difference between re or rh too. But it was definitely worth mentioning in case someone else out there is reading and wondering. But the difference between a 42 and a 44 wouldn't be noticeable from outside if you had 1 of each sitting on the bench.

Same deal between a 46 and a 47.
