I have a Suzuki Jimny automatic 2007. It has 3 buttons to select gear type. None of these are now working.


Start by looking at the fuse box... check all the fuses. Next possibility is a relay.

The Suzuki Jimny Transmission Control Module (TCM) is an electronic circuit component that controls gear shift, TCC lock-up and idle-up according to the signal from each sensor. It is a microcomputer consisting of an IC, transistor, diode, etc. It is installed behind glove box.

1. Ignition switch
2. Transmission range sensor
3. Input shaft speed sensor
4. Output shaft speed sensor (A/T VSS)
5. Shield wire
6. Vehicle speed sensor (VSS)
7. Transmission fluid temperature sensor
8. Shift solenoid-A (Shift solenoid No.1)
9. Shift solenoid-B (Shift solenoid No.2)
10. Shift solenoid-C (Shift solenoid No.3)
11. Shift solenoid-D (Shift solenoid No.4) 12. TCC solenoid (Lock-up solenoid)
13. "O/D" cut switch
14. "O/D OFF" lamp
15. Monitor connector No.2
16. DLC
17. To ECM
18. To A/C
19. To brake lamp switch
20. To main relay
21. Terminal arrangement of TCM coupler

Why does my automatic suv slow to shift gears?


It does not slow actually , in the process of shifting gears it ( gear box) momentarily stop transmitting power to drive axle.

Rough shift while getting up at 55mph


with auto tranny, when you relieve the acc pressure on the tranny it will drop into a higher gear, this is normal but if your road speed is low and you put your foot down hard it may change back 3 gears, it decides what gear it requires in relation accelerator pressure and road speed, the tranny does have a switch near the selector, this lets every thing know what you want it to do, this is adjustable but can fail also

My check engine light its on.. on my 06 mini cooper.. the codes are p1787, and 1698... can someone let me know what this means??


P1787 AUTO box ecu failure
P1698 Bipolar stepper motor short circuit

It can also mean that you must carry out an auto-box relear procedure

Mini Cooper Transmission Relearn Procedure


If the gear selection display on your Mini Cooper has an x before the gear selected,

like xP or xD or xR, then you need to run this procedure.

The usual cause of this is a dead or disconnected battery for a long period of time.

First make sure you have a good battery that will hold a charge or fix the charging

system problem.

Get the car someplace where you will be able to drive for a mile or two without

interruption on a fairly level road.

Follow ALL steps and don't skip anything.

Clutch Adaptation

1. Begin with a cold engine and start the car. Shift to N for 10 seconds, then shift

to D for 10 seconds.
Shift to P. Display says xP.

2. Repeat the following ten times. Shift to N for 3 seconds, then shift to D for 3

seconds.
Shift to P. Display says xP.

3. Repeat the following ten times. Shift to N for 3 seconds, then shift to R for 3

seconds.
Shift to P. Display says xP.

Step-up Ratio Adaptation

1. Accelerate vehicle to a speed greater than 80 km/h. Don't be afraid to go above

the redline on the tach for a few seconds. At this point the car may buck and snort

a little as it tries to get into a higher ratio. As soon as it settles into a higher

gear and the revs are above 4500, rpm let off the accelerator quickly. Don

Shifting out of first takes longer and feels rough


1-2 shift is delayed and harsh, may not shift into OD: Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace.

Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check TPS for smooth electrical response. If the response is jumpy or erratic at all, replace TPS.

Extremely harsh shifts from P or N, normal shifts at WOT: EPC (Electronic Pressure Control) solenoid failed. Easy fix in pan. Fix as soon as possible or hard parts will eventually break.

Visit a transmission shop and have them put a line pressure gauge on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.500" boost valve (easy fix in pan).

Here is just a few things that are common to what you have described, I would start checking the Wire leads to the TPS and TPS it self. Good luck and keep me posted, be glad to know you got your Transmission running 100% again.
