Band adjustment, how many turns out on 1987 300zx

Bands are adjusted when you build a transmission

You do not need to adjust

The amount of band thickness & wear, is so small,
that the trans is shot, long before you have any wear
that needs to be adjusted

If you turn the screw the wrong way, the band falls off at
the ends & you can't reach in there to replace it & the unit
has to come out & apart

You will see no difference if you brought that band down tight
on the drum & then loosened it the correct number of turns

The servo will apply the band & there is no reasons for a delay

Your 2001 is 13 years or more old

If the fluid has not been changed every 2 or 3 years
since new,it is about to expire

Check your fluid level. Then for physically taking action, some models have adjustable transmission bands inside the trans. These may be reached inside the trans when changing the screen filters or cleaning them. Some models have external adjusters. Typically involving tightening the bands to a certain torque amount and then backing off the adjuster a specified number of turns.

There are some chemical additives of questionable value claiming to fix these problems.

I would go to 3 places for estimates. Some transmissions have no adjustments and your trans may be on its last leg. Used transmissions out of a wreck or a Rebuild may be options.

Band adjustment is very sensitive on these units, I set both adjustments at one turn. This is a 4 speed trans that has been converted to a 5 speed by turning on the od unit ( 1-2 shift ) in first gear.the 2-3 shift is busy because the od band is coming off causing the od unit to transfer back to 1:1 and the intermediate band is coming on . I have found that if the overdrive band is to loose it will release to fast causing a flare on the 2-3 shift bot not really affecting the 4-5 (overdrive) shift. So break both band adjustments loose and tighten the adjustment screw down and back off 1 turn the tighten jam nuts. Also the fluid level should be checked with the transmission warm ( 100 f , not hot, not cold) and the fluid should stream out of the check tube. Transgo makes a really nice vb kit that i use that will help these symptoms.

The correct fluid to put in a 1997 van is (ATF-3). Sounds like you need to make adjustment on both the forward and reverse bands of the transmission to correct your problem. The kickdown band (front) forward is located at the top (outside) of the transaxle near the front. To adjust the band,loosen the lock nut approximately 5 turns. With the lock nut loose the adjusting screw should turn freely in case. Tighten the adjustment screw with an inch lb. torque wrench to 72 in-lbs. Then back the screw out 2 1/4 turns, hold the screw in place and tighten the lock nut to 35 ft-lbs. Then after removeing the transmission pan and filter the low-reverse band is located next to the valve body. Loosen the lock nut 5 turns so the adjustment screw is free. Turn the adjustment screw in to 41 in-lbs, then back the screw out 3 1/2 turns. Hold the adjustment screw and tighten the lock nut 10 ft-lbs. Install transmission pan/with gasket and refill transaxle to proper level. Test drive van. Be safe and block the rear wheels before you raise the van and try to work under it. Hope this will help you.

check fluid if burnt or brownish change filter if it hasnt been changed may be problem -- no external adjustments on tranny to replace a band-valve body- gear -clutches have to tear down trans

just drop the transmission pan to drain it and the filter is right there in the valve body,DON'T mess the band adjustment,they are only to stop the planetary gears so you can go into reverse,there is no such thing as adjusting bands! that went out with the fifties!

there is no band to adjust for your problem,the only bands are for stopping movement in the trans to to go to reverse,if your transmission is whining it is a problem with the front pump assembly ,

check fluid level AND condition...should a red color...if its discolored, in any way, flush it and change the filter too...then perhaps there is a band that is out of adjustment allowing the flare up, and it suddenly grabs getting the hard shift....or else trans is worn out....check the fluid

The proper fluid for that Tranamiaaion is Mopar ATF Plus 3 Type 7176. I recommend using it as I have found it does make a difference.

LOW-REVERSE BAND:

1. Loosen, then back off lock-nut approximately five turns.
2. Tighten adjusting screw to 41 in.lb.
3. Back adjusting screw off 3½ turns, then tighten lock-nut to specifications

KICK DOWN BAND
The kick down band adjusting screw is located on the left side, top front of the trans-axle case.

1. Loosen lock-nut and back off nut approximately five turns. Ensure adjusting screw turns freely in the trans-axle case.
2. Using tool No. C-3880-A and adapter tool No. C-3705 , or equivalents, tighten band adjusting screw to72 in.lb.
3. Back adjusting screw off 2¼ turns, then holding screw in position, tighten lock-nut to specifications.

Good luck and keep me posted, be glad to answer any other questions you may have.

the trans has a serious failure, that is why the metal, it can be overhauled for less than a replacement
