Jeep TSM Powertrain-Driveline Combinations chart list the CJ7 & 8 with the TF999 exclusively and the Cherokee models 16,17,&18 using the TF999 behind the 258 but the TF727 with the 360. The Wagoneer model 15 is shown using the 999/258 combo but with the 727 behind the 360. The truck models 25 & 26 are the same combos and the model 27 truck as having the TF727 as the only available auto.
Section 2C Automatic Transmission states "Two automatic transmission models are used. They are models 999 and 727. Model 999 transmissions are used with six-cylinder engines in CJ-7 and Scrambler models and Cherokee, Wagoneer and J-10 Trucks with a 2.73 axle ratio with a six-cylinder engine. This transmission has a wide ratio gear set with a low gear ratio of 2.74 to 1. The model 727 transmission is used in Cherokee, Wagoneer and Truck models with six or eight-cylinder engines."
The TF999 began service in the FSJ in '84 but only behind the 4.2 and is the one I referenced for my prior reply.

The TF 999 was first used in the FSJ in the '82 model year but again only with the 258 I6. Also note the TF 727 was introduced into the larger line of jeep vehicles in '80 on all V8 engines and then improved w/lockup converter in '81 and was continued until the SJ's production ended. Further down the list is a year to year list w/notes referring to the two transmissions in question.

The TF 727 was a H.D. option in the big cars and the Wagoneer w/6 cylinder engines from '80-83 and in the Grand Wagoneers from '84-'87. Note the reference chart indicating that the 727 was used behind the 360 and the 401 and as an option on the 258, with the 998/999 being used w/232,258 and the 304 AMC engines. Further down the page the TF 999 is listed as being used with the 360 Chryslers, and possibly also in later FSJ's.

On the FSJ FAQ charts we see the TF727 was the auto for all AMC 360's from '80 until the end of production and was also used with the 258 with the 3.31 axle ratio during the same period. This said the TF 999 was used behind the AMC 258 w/ 2.73 axle ratio from '82-'87 and was not used in the J-20. Here we will see a reference to the N.P. 208 as being standard on all manual transmissions and used with the 6-cylinder with auto trans. combination. Lots of very good information on this site for jeepers.

A good FSJ site with great information on the Drive Train Components used from '62 until '92.
Trans usage listings, V8 w/727 and the I-6 w/999.

FSJ (SJ and J series pickups) link listing the TF727 usage on the '80-'83 I6 and V8 and then '84-'92 only with the AMC360 V8, but listing the TF999 being used in the '80-'86 CJ and was also used in the '84-'90 SJ's and J series trucks with the 4.2L, in the YJ until '91 w/2.5 and 4.2 engines and in the XJ and MJ through 1986........

===============================================
TF-999 Band Adjustment:
The 'Arrow' is pointing to the 1st/Rev. band adjuster, and it will be located in the rear/right (passenger) side of the transmission.

This shows the 1st/Rev band, and it's the MOST common problem with Chrysler transmissions...
The idea is to back the JAM NUT off about 5 turns or so,
Adjust the center rod,
Torque to 72 In.Lb. (that's INCH pounds, not foot pounds!),
Then back the adjuster rod out about 2 to 4 turns, depending on what transmission you have,
HOLD THE ADJUSTER ROD FIRM while you tighten the Jam Nut back up.
That's all there is to it!
---------------------------------
There is a second band adjustment on Chrysler transmissions,
The 'Kick down' or 'Overrun' clutch band...
And I don't have a picture of it's location, but it's adjustable with the pan in place, the adjuster is outside the case.
Again, it's an Adjuster Rod with Jam Nut arrangement,
It will be on the drivers side of the transmission (Left Side),
Just above the shifter/kick down linkages attachments.
And again you will need to apply 72 In.Lb. to the ROD, then back the ROD off 2.5 turns,
And lock down the Jam Nut WHILE HOLDING THE ROD IN PLACE!
