Get it fixed, are you going to diagnose and repair and A/T?
that car is a 1/2 GM/ Daewoo car. a sad mix of parts. (sell it? i would )
the service book is here. $4
This is called an FSM.
https://suzukipitstopplus.com/Products/1068-2007-forenza-reno-service-manual.aspx

783 (p07xx means tranny issues)

quote FSM:
Trouble Code: P0783 (2.0L L4 VIN - Auto)
3 - 4 Shift Malfunction Print this code dataI Have a 2007 Suzuki Forenza with a winding in the - print_icon_codes.gif comments in (xxxx)
Trouble Code Conditions: (preconditions before test)
Transaxle oil temperature is greater than -10 °C (14 °F). Selector lever is not N (Neutral), P (Park) position. (warm , in gear)
System voltage is greater than 9 V.(car battery not dead)
No input speed error DTCs P0715, P0716 and P0717.
Speed sensors not dead.
Output speed is greater than 256 rpm. (tail shaft rpm (speed)
Input speed is greater than 400 rpm. (engine rpm after clutch)
3 - 4 gear shift is active. (the TCM commands shifts to 4th)
Possible Causes:

  • Circuit to solenoids bad.
  • ECM, bad.
  • TCM bad or inputs wrong.
  • end quote.
Comments:
this means, in pure physics.:
the transmission slip's
what that test failure means it bar stool talk is this.
I shafted to 4th but the MPH is too slow, so the transmission
is not shifting to 4th , or it slips

any mech would drive the car first. (did he?)
and flog it up hills (in Kansas? omg)
TO SEE, if it slips in 4th or fails to shift at all.

  1. fresh ATF? and filter? serviced and levels good on A/T
  2. is the 4th gear command to the shift solenoid good.?(logic)
  3. if trans slips? (fails FSM book stall tests) bad tranny.
  4. if the trans fails stall , check line pressure per FSM.
like that, and more, lots to say on A/T
If in uSA find a real , shop, with ASE techs. and win.

SOURCE: need to know how to adjust transmission newly installed.

What model truck is it? If it had a vaccuum modulator it is adjustable. If it has a throttle valve cable it too is adjustable. You should not drive it much till all adjustments are made, this could result in damage.

your mechanic should have test driven so you had to do it the hard way. Take it to a mechanic who has equipment to diagonose the problem because these cars ar highly computerised.

SOURCE: What could be causing my 1990 Chrysler Lebaron With auto trans to wind out to long and not shift properly?

Have you checked the automatic transmission fluid level??. Has the fluid and filter ever been changed on the car??? If that is okay, then you're going to have to go to the shop to find out what's wrong..

On my 2007 suzuki forenza the check engine light came on. i had it troubleshooted at autozone, and the computer indicated the transmission range sensor out of position. where is it located?

no such code on that car, auto zone uses global testing which pulls universal codes, so that code means someting different for the suzuki, need to have it checked by the dealer or a shop that has import software, or post the code # and i can translate it into import code, good luck.

The catalogue of original parts for the suzuki forenza 2004 is necessary to me

Go to oemsuzukiparts.com---they have every oem part since they apparently are a dealership that sells very inexpensively yet original parts online. I have used them to buy struts, rear headlights and transmission range selector switch with no problems.

2006 suzuki forenza. automatic transmission. Check engine light came on. transmission would not shift out of 4th gear. on a hill or level surface only in high gear. could it be the module on the...

Was your issue the range selector switch (a.k.a. range sensor, prindle switch, park/neutral safety switch). Part # 37720-86z01?

It is located on the outside of the transmission on the front side (not between the transmission and the firewall). You can open the hood and put an eye on it.

Be VERY sure to alignment it properly AND to clear the code.

If this helps, please say so!

A square with a diagonal line appears instead of the shift (P R N D 3 2 1) please advise... thanks

This means your transmission range selector sensor has gone bad. This is a very common problem with Suzuki's. You can buy the part at oemsuzukiparts.com for about $35.
