1995 Suzuki Sidekick JX Shifts into second gear hard Automatic
Hi, my 95 JX automatic sidekick recently started shifting into second gear hard.Suv has 213,000 on it this just started happening.Any Ideas on what can cause this?I checked fluid in tranny it is full but could use changed.Feels like the gas pedal goes down a little when it shifts like it losses its tension or pressure .Just put new rear end seal in it because of leak but problem was there both before and after that.Thanks in advance
the easy list.
check the kick down cable for jam or break.
check modulator valve for fluid leaking form vacuum nipple when hose is removed.
full power flush and clean bottom screen or new filter if it has one. (and pray)..
for a better diagnosis give all things it does correct and incorrect , up and down.
and any delays to go in gear or out to neutral.
collectively they tell a story.
hydra-matic 3L30 ( get a new filter , clean pan , full flush on any auto that fails)
no one ever does Auto tarnny maintenance and the 3sp is every 15k !!!
It is a dirty dog is why.
does it do that cold , starting in any other gear, including 1 , or D. ? ( not go?)
to get a good diagnosis on any auto , what it does correct is just as important as what it does wrong.
there are 6 pages in the fsm for on car tests.
there are 6 page in the fsm for faults.
i will give you the title , you tell me what most applies,?
one liner, squacks:
no starting in any drive range.
starts in drive range, only after repeated movement of selector lever.
nostarting after shifting lever from P , to D or L2 or L1.
sudden starting oly after engine rpm increase.
heavy jerking hen starting.
no starting in D or l2 but in L1 and R.
no starting in D , L2 or L1 ,but in R.
no starting In R , but in all other ranges ---- bad reverse clutch.< you ?
starting in N.
one idea , cold dirty fluid will never go thru a dirty filter so pump pressure will be bad.
pull the factory listed procedure on the car before it is too late.
btw : the first question in the flow chart, is the fluid dark and does it smell burnt.
should smell sweet.
it has 1000 parts in side, and is non too simple .
I say , filter is clogged, some 3sp have only a screen that clogs.
1995 Suzuki Sidekick, 4spd automatic with hard bump shift
I have a similar problem.
Hi, I just purchased my first Sidekick, a 1995 JLX 4 door with a 4 speed (3 plus overdrive) automatic with 106K miles original.
ATF was brown (possibly never been changed) but not burnt and ½ quart low. (I’ve now changed ATF).
Tranny shifts hard bump 1st to 2nd.
Coming down from 2nd to 1st also hard bump
Also hard bump engaging tranny from N to 1st & from N to R.
When stopped in 1st, 2nd, or D vehicle pushes against the brakes to move forward more than normal
Also stopped in R vehicle pushes against the brakes backwards more than normal
Shifting from D to N produces a “hard” release
Also shifting from R to N produces a “hard” release
No delays in shifting, just hard shifting at noted locations
Overall it seems like too much hydraulic pressure at these locations
Auto shifting from 2nd to 3rd and to 4th and back down to 2nd all seem normal
Kick down cable seems OK
I can’t find tranny modulator valve – is it external or internal?
Could there be a problem with #1 shift valve (solenoid)?
I purchased a new screen filter and pan gasket and plan to install but would like to install any other necessary internal parts at the same time.
I would greatly appreciate any knowledgeable help with this problem, Thank You
Modulator valve is external, and sounds like your problem. You will see it just at the tranny pan, and I believe you need to disconnect the front prop shaft ot get to it. You can remove the vacuum line to the modulator, and check if there is any fluid in it (it should be try). In order to get the modulator off itself you will either need a special (very thin) wrench, or search the forum as a few of the posters have ground down a wrench to fit this connection. With the modulator off the car, you hold it with the stem pointing downward, and if tranny fluid comes out of it then the diaphragm in the modulator is defective.

Hi Bex, and thanks for the reply. Are we sure we are referring to the same tranny? I believe this might be the Suzuki 4L30-E and not the GM Hydra-Matic 3L30. I yet cannot find the Modulator valve on the external right side of the tranny (not on left side either). Perhaps because it is the 4L30-E (4spd, Lateral, 30 torque, Electronic) then it might use an electronic internal Modulator valve rather than an external Modulator valve??? I took photos of the open tranny and it is stamped ASIN 8963-15 under the filter screen. That is the only ID I could see. There appear to be three valves/solenoids (1 up front and 2 at rear) inside the pan area. Is there a way to test these valves/solenoids without removing them? I would be glad to remove them and test them if that is necessary. Also, do you think there could have a faulty Transmission Control Module (TCM)?
Transmission was super clean on the inside
ATF filter/screen was also very clean and no iron particles on pan magnets
For tranny ID purposes the VIN is: JS3TD03V7S4112591
Oops. Sorry. No, the 4 speed does not have the modulator - its shifted by its own TCM. Is the O/D light on, showing that the TCM has codes in it? I'm not too familiar with this complex tranny. If no one else can help you, I think that the FSM on Acks FAQS has a section for the 4 speed tranny that might help you. Ack's FAQ Site Map
