Thanks for the great write-up.

Will I find the wrench sizes to be the same on the wife's 91.5 A518 as described for the 89 727 ??

I was looking a write-up for a 1994 and it shows torx-headed screws for the band adjustments.


Also, how many quarts of fluid should I have on hand ??

Thank you.

72 inch-pounds = 6 foot-pounds, right ??

Thanks.

I havent looked back in this thread for awhile now but I can tell you my 93 (w/ original trans) had a square, drain plug style head for band adjustment. I think it was an 8 point 3/8" socket if memory serves.
My dads 91.5 that had a Chrysler reman tranny installed, by the *********** in 2004, uses torx fittings

Hey all,
On the topic of adjusting your bands. Does anyone know if there is a detrimental downside to adjusting only one of the adjustments? I have a slight shudder I've been chasing and am going to try adjusting the low/reverse band (which is the one inside the unit correct?) to see if it helps at all.

I just completed this maintenance chore and the advice in this thread was invaluable. I'm convinced that, if not for this website, my truck would no longer be still on the road. Thank you!

A couple of observations:

• For adjusting the front band, an 11/32" 12-point socket for the adjusting screw and a 3/4" socket for the locking nut worked great.
• For adjusting the rear band, the locking nut was 11/16" rather than 3/4". My dad bought my truck new, so I'm fairly certain these transmission parts are all OEM.
• For the rear band adjusting screw, a 5/16" 12-point socket was too small and an 11/32" 12-point socket was too large . Even in a city the size of Atlanta, I could not locate a 5/16" 8-point socket on short notice, so I welded up a square socket that worked fine -- 72 inch-pounds is not a lot of torque. I have since ordered and purchased an 8-point socket from Grainger.

I adjusted the shift points screw and the line pressure screw by about a half turn each (CW and CCW respectively). My truck has 130k miles and I figured a small tweak wouldn't hurt.

Again, thanks to all for the excellent photographs and detailed instructions.

Hi there,

It's a great article because the instructions are so clear. Myself I was very excited to read it, but now I'm confused about what dzl_damon was actually trying to accomplish. I get the line pressure part -- it gives firmer shifts -- but the rpm part confuses me.

Myself I have a 46RH and want to bring my 1-2 shift DOWN in rpm. At the moment the rpm climbs to exactly 3000 before it shifts from 1st into 2nd. That's way to high. I have just completely a complete transmission overhaul and it's not shifting the way I want. I'd like it to shift from 1st into 2nd at 2000 rpm.

Is dzl_damon also trying to bring his shift point down? Is that what the first "2 full turns CW" are for? That first screw is actually called the "throttle lever stop screw" and the procedure is called "Throttle Pressure Adjustment".

Actually the FSM says nothing about what CW/CCW does exactly. I have both the 46RE 2002 and 46RH 1993 FSM and both have the identical pictures and text about the "Throttle Pressure Adjustment".

It seems dzl_damon is not longer posting to this forum :-(

Can someone clarify what screw to turn which way to reduce the RPM of the shift point. I'm speaking about he non-WOT case.

Best wishes

are re you still doing transmissions. I know this post is old, but I can't find a Diesel trans shop I trust

go to the local drag strip and ask some of the racers who they recomend, then just have the guy put in an HD kit, shift kit in the VB, and a really good converter and it will be good.

the autos in our trucks are basicly the same ones that were in dodge cars and trucks in the late 60's

I know this is a pretty old thread but I found the information and pictures useful and wanted to add a piece of information. Sorry if this is conflicting but I think its worth noting

The 1993 factory service manual on page 21-140 it talks about this adjustment and states that "one complete turn of the adjusting screw changes line pressure approximately 1 2/3 psi". so based on that 2 turns would be approx 3.3 psi
