Transmission Help (no reverse or drive)

[EXQZME]

Well let me say that I didn't think I would be asking for help this soon again guys.
but last night while I was driving home I was getting on the freeway (uphill on-ramp) I tried passing a minivan that was obviously not trying to speed. When i gave the ls a lil more gas i noticed that it wasn't downshifting to 4th or whatever gear its supposed to be in while going 55mph. I gave it more gas and nothing then i did probably 75% throttle and it finally downshifted 2 gears (3rd i'm guessing). Approximately 1 second into it the car just rev'ed up like if it was in neutral. After about 5 minutes trying to figure out wth happened it finally moved when i put it in D1.

So the thing now is that it wont move in REVERSE or D5, D4 it only moves if i manually do it from D1 to D2 to D3 and so on.
I have never experienced this before on any car. Where should I start???

04 v6.

What has been done to the transmission recently? Was it correctly filled after that work?
Is the check engine light on? What are the codes?
Does it say "E" in the gear selector display in the cluster?

 

[EXQZME]

No work done to the trans that I know of or since i've had it (8 months). I was actually planning on taking it to a trans shop last week so they can check fluid levels and stuff but then this happened. It feels like i jinxed myself.
No check engine light.
The only thing that is on is the "service parking brake" and that has been on ever since I got it. I drove it down the street right now and was trying to manually shift it but it seemed to not read the correct gear i had it in. (i was on D4 and on the display it said D5")

 

[EXQZME]

could it be low trans fluid? i checked under but didnt notice anything dripping from or around transmission.

 

[joegr]

It sounds like at the least, your shift linkage and/or digital transmission range switch are out of adjustment. Low fluid would account for some of the symptoms, but not the wrong gear indication. A problem with the linkage or switch could account for all of the symptoms.

BTW, there is No D1, D2 or D3. If you select 1, 2 or 3 that is the only gear you get. The trans will NOT up or down shift.

My shifter blew a diode years ago and D4 wasn't selectable even though SST worked perfectly. New shifter (under warranty) and everything was back to normal.

He has V6, so no SST. It should really be D5, D4, D3...

But the only "D" gears (1-4 or 1-5) are D4 & D5. The others are just 3, 2 & 1. If, say 3rd, is selected, the transmission will stay in 3rd gear until another is selected. It won't up shift (will hit the rev limiter) nor downshift.

Oh, I see.

 

[EXQZME]

Yea sorry for the D1, D2 and D3 reference, I guess I was just trying to generalize.
So I had the LS parked all weekend, I drove it down the street and it wasn't going past 2nd gear on 3, d4, or d5.
Right before I shut her off, I noticed the "E" in the gear selector display.
I plugged in the scanner and got code "P1700"?? Is this game over?

Just to be clear, if you select 1, 2 or 3 that is the ONLY gear you will get. Like I said above, the transmission will neither up nor down shift.

As to code P1700 Google says......

P1700 Transmission intermediate failure (failed to neutral)

 

[EXQZME]

I understand how the 1,2,3,d4 and d5 work on this car.

The thing is that this time I went from 1 to 2 and when I shifted up to 3, it still stayed in 2nd gear. Then I went all the way to d4 and d5, it was still not getting out of 2nd gear. I was also looking at the gear selector display and it was displaying all the correct gear changes I was making, but no gear change was actually happening.

regarding P1700, thats what I found too but I kinda knew the problem is related to the trans, so this code didnt help me by telling me the trans is failing. haha
is there another way to get a bit more detail of what failed in it?

Got it......

I am having the exact same problem. It started on Friday night had it towed Saturday morning to a transmission shop

 

[joegr]

P1700:
Internal component failure. Direct one-way clutch failure.

FMEM becomes active — engine rpm limited to 4,000 rpm. Failed a neutral condition in 1st, 3rd or 4th gear in automatic mode. Only 2nd and 5th gear available. Other DTCs that may set P1700: P0745, P1747, P1760, P1714, P1715, P0750, P0755.

If other solenoid DTCs are present, diagnose and repair them first. CLEAR DTCs and drive vehicle. If P1700 returns, disassemble transmission and inspect the direct one-way clutch. Repair as required. CLEAR DTC. Drive vehicle and verify repair.

 

[EXQZME]

Well it looks like this problem is well beyond my mechanical knowledge and abilities.
The most I got to inspect was the trans fluid which came out dark brown.
So I'll be taking it in to local trans shop and see how it goes.

Not good.

Hmm mine is not showing any codes. Check engine light is not on and the E did not show up on the display where gears are displayed. Transmission shop called me back for the information on my warranty and asked for my permission to open the transmission up. Probably wont hear back until Friday

This is why I dislike it when someone jumps into a thread and says "I amhaving the exct same problem." Usually, as in this case, they really mean they are having a similar problem, but not all the symptoms match. This does not fit with my definition of "exact" or "exct."

 

[EBK]

It has all the same symptoms I can not go anywhere in Reverse or In drive. if i put it in select shift mode I can move it in second gear. (yes i understand yours is just an auto trans not select shift however manually selecting a gear worked for you as well ) minus the code. I also didn't drive more than 100yards after the issue occurred so it may not have had time to throw a code. i was parked and towed to the Transmission shop the next morning. They may have gotten the E code or the p1700 I dont know. So minus the Code it is the Exact same problem

The ONLY difference between SST and non-SST cars is the shifter. The transmissions are identical.

I still don't think that you know what "exact" means. Anyway, use the advice that comes out for a problem that is similar (but not exactly the same) as yours at your own risk. Understand that different problems can cause similar symptoms, but the exact solution may be very different.

The problem its self is Exact match to the OP's Only difference is I Don't wait for a code to tell me something is wrong or take mine out for a drive after I KNEW there was a problem to make the code come up. That code More than likely came up for the transmission shop I had it towed to so I really don't see what your problem is aside from a poor attitude.

 

[joegr]

I disagree that it is an exact match. (I by the way, don't have an transmission problem.) I was just trying to get you the best help possible. That was, I guess, a mistake that I will now correct. Sorry to have bothered you.

 

[EBK]

The fact I didnt drive it long enough after the issue to get a code does not change the symptoms. My symptoms are I am able to put it in reverse and drive but when I press the gas I get no response aside from RPM increase, no power to wheels. When 2nd gear is manually selected ( 2000 so can not select first gear) it will move. So what about that is different from the OP?
