Code P1700 (SVS Request Viacan)

since this to do with auto transmission perhaps take it for repair.
https://www.carparts.com/blog/p0732-code-gear-2-incorrect-ratio/

your vehicle sounds like its auto. that p1700 fault code is tcm (transmission control module) service request and does not mean a fault is present unless the gearbox fault light is on then there will be a further fault code present to indicate the problem area

need to plug it into diagnostic machine to get further
fault code and go from there

i have a 98 accord v6 vtech 3.0 i hve a code 1705 neutral safety switch i changed it nd still stuck on 2nd nd 3rd gear. can any1 help me out

try getting the 2-3 shift solenoid from your local auto parts store. that's usually the case when it won't shift into 3rd gear.

It is possible that the synchronizer from 1/st to 2/nd gears is finished, this is not a repair that you could do by yourself as it may require the special tools and the setting of a shop to work underneer of the vehicle.
If you take your car to a transmissions workshop, they will test it with a computer and determine what the cause is of this behaviour may be. If it is a matter of synchronizers, it will be very wise to exchage all of them, once the tranmission is dismantelled.
That work, may take three to four days to be repaired. The more time you take to fix this problem, the worst the failure will become.

Good Luck...!

Hi, It may be in LIMP mode.

What is "limp-home mode" ? This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

Common failures on 4L60E, symptom any possible repair:

Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under-hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter :ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Trans seems noisy when moving in 1st and Reverse, noise goes away instantly if you shift to N or the trans goes into 3rd gear: Reaction planetary is worn out due to high miles or insufficient lubrication. Not a critical failure, but not a good sign either. R&R sooner rather than later.

3rd gear starts, can manually shift through all gears. When car has been turned off for a bit, then back on it will run normally.: VSS dropoff w/ Hi-stall converter. The rpms are too high, but VSS is showing no movement. Happens after a tire burning take-off. Doesn't store a code, will not throw a CEL (I've heard that it will store a code if it happens 3 or more times). Cure: Reprogram PCM for VSS dropoff -- PCMforLess knows about it.

If you can get the Jimmy for no more then $500.00 and the engine sounds good and body is good, you may want to invest in the repair of the jimmy. Also note that to have a close look at the fuel line along the frame on the drivers side just by the back doors, the line is know to corroded there on all the SUV's

is your linkage Bent to the transmission ?

Or perhaps something under the boot obstructing from engaging into gear

belt inside trany is slipping rebuild or replace trany

when the eml lght flashes it is normally detecting a missfire but could be an intermitant missfire as vw's also do this

you need to have the car read with a diagnostic computer

hope this helps
