Back on my Mustang this how I did its band adjustment.

Loosen the jam nut.

Torque the adjusting screw/bolt.

Put a mark on the screw, if needed.

Then using an open end or box wrench, NOT A RATCHET, to back out the screw.

For a 2-7/8 turns - turn the screw 2 full turns out, stop, now turn the screw out 3/4 turn, stop, now turn the screw one half of a quarter turn.

Hold the adjusting screw and tighten the jam-nut as needed.

 

I find it curious that the same transmission can be so different year to year on adjustments and in 1996 the 46re and 47re are the same adjustment? According to my 1996 FSM that is correct, but it just seems odd. With each year so different, an early model could have last year's trans or a late model next year's trans and the wrong adjustment could result in a big problem. If someone replaces their trans, what adjustment would they go by, the year they replaced the trans or the year of their truck? Is an August 1998 transmission manufacture date a 1998 or 1999 adjustment. Perhaps folks having issues with their trans after adjustment are just having issues with using the correct adjustment. I use the FSM adjustment specs for my 1996 V10 / 47re and it seems fine, but after looking at the chart and knowing mine is a 1/96 manufacture date I wonder.

 

My thoughts exactly, it all sounds kinda wish washy to me

 

i would say that it has to do with little things like different vehicle weight from year to year and also performance adjustments (like divided kegger and non divided kegger).

That makes the torque and stress on the tranny different for shifting. That is just a thought.

 

That makes sense CPTAWF163; there are subtle differences between the years like that.

Has anyone ever tried to deciper the code on the trans just above the pan? My FSM says it should be
XXXXXXXXXX XXXX XXXX with the first 10 numbers the part number, the next four the build date, and the last four the serial number. Mine is not set up with the 10 numbers + 4 + 4, its 14 + 4. The number is
PK521184342582 0788. Not sure what a build date of 2582 would mean for a 1996 truck!!

Anyway, I'll stick with the regular maintenace as it shows in my FSM with both bands: @ 72inch pounds and back off the front 2 7/8 turns and the rear 2 turns. I also have a subscription to ALLDATA and they show different numbers for the 47RE: backoff 1 7/8 front and 3 rear, but the above for the 46RE.

 

i dont have a 1/4 inch socket will any thing else work or is there a dirrrent wayof doing it

 

I am not going to gamble with this one. I am going to take the truck down to trans shop, do a service and adjustment is included.

 

someone stated that many of us have issues AFTER adjusting the bands. When my transmission got rebuilt about 2 months ago I specifically asked about adjuting bands when I service the trans and the response I got was don't do it unless something is wrong. I'm not saying they are right, all I'm saying is they are professionals and that was the advice I was given. Since then I have asked other mechanics that I trust and they all say the same thing? So maybe this was a habit that was formed at some point because of an issue that isn't needed anymore? I'm not sure what I'm going to do when it's time to service it!

 

Get the required equipment or let someone who knows what they are doing take care of it.

 

+1. Sometimes spending 50 to 100 bucks to get it right and not burn up a 1700.00 transmission.
