i have a 2004 Suzuki Grand Vitara v6 4x4 4 door auto,
I dont have money to take it to a shop was wondering if any of you have experienced the same issue,
it will only shift from first gear at 5000rpm and it kind of slams into second only code i have is p0720 replaced the sensor and checked wiring, can verify i have live speed signal on spedo and a obd2 scanner, it doesn't lose power at all and it pulls the entire time no slipping as far as speeding up, once it shifts from first all other gears work fine and downshifts normally. if u stop at a stop sign for example it does the same thing it just wont shift from first when its supposed to, im kind of at a loss here and dont know what else to do or check,
i have tried a different Computer didn't change anything,
the guy i traded to said he has drove it like that for a year, if i clear the code it will come right back after it revs to about 4k Rpm, the car is really strong and in first gear i can pull up a steep hill and it doesn't slip at all.
the trans fluid is red and after multiple attempts at fixing it and test driving it i can smell the clutches burning in the fluid now i have had it parked so i dont risk making a problem worse.
it also doesn't change anything manually putting it into second on the shifter it just stays in first i havent seen or experienced anything like this, ive always had manual vehicles ive only owned 2 autos and they never gave me issues. so if any of you have any clue what this could be or maybe tell me something to look for or a way to test it i would really appreciate it.
It sounds like your transmission is worn out (clutches burning). You did not mention mileage but it is really no surprise after 22 years.
You could try some snake oil like Lucas "Transmission Fix". It would not actually "fix" anything of course but some have reported temporary relief with that kind of product. It might give you a little more time to shop for another car.
Well Those Suzuki automatic transmissions are known to be terrible as they age. One of the big reasons they stopped selling Suzuki cars in the United States as most people drive automatics. And it obviously has a problem in the side the transmission. But I've never even met any transmission guys here in the United States who would even work on the things. They can't get parts. They're extremely complex to rebuild. You would have to go to a Suzuki transmission expert if you could even find one and then you'll probably find us more money than the cars worth trying to rebuild it from my experience
