Transmission issues and questions

[AuSeeker]

so i ahve a somewhat similar problem, but in mine..usually happens btw 25 to 40mph, when i try to accelerate, i would be giving it gas...and the truck would not respond, the rev meter would also not go up either, so its a bit confusing if its a fuel delivery issue or transmission issue-- i thought if its transmission related, the rev would go up, while the car refuses to increase speed/change gears.

also that white connector you talked about is a real PITA to acccess, i have tried so many times. next option am considering is to cut up the car sheet metal from the inside and access the connector directly.

what do you think?

I think it's unnecessary. I'm a bigger guy with clumsy arms and I was able to access the connector to do the de-oxit treatment.

Now, don't get me wrong. It's not right out in the open like a lug nut or spark plug, but I think it would be far easier to prop up a flashlight and contort yourself a bit as opposed to removing carpet, cutting a hole, then sealing it back up.

I agree that it not worth cutting a hole, first off you would have to cut a rather large hole to make it any easier to do from inside the vehicle, you still will have tight access to the connection and then have to bent it all back, tack weld it reseal it, not to mention removing everything to cut the hole and put it back, no way I can see thus being easier then doing it from underneath.

Follow up with this
Whole issue may have been my front wheel bearings.
Initially started out with the rumble strip sound.....
Eventually I heard a noise, maybe like a pop....
And then sound just got worse

So began to thank rear axle wheel bearing.
Took it to Firestone to be sure and let them diagnose.
Glad I did....
Turned out to be driver side wheel bearing...totally bad, but no wobble with the tire when lifted.
Mechanic said the passenger side was also on the way out the door.

So bought Hub and Bearing assemblies from AutoZone, swapped out both sides.
Truck rides smooth, sounds is gone.

Waiting on my CVJ Axle to come in so I can do the passenger side....

And another follow up, to round off this square.
CVJ Axle came in, replaced. So that is all good now.
Did another ATF drain and fill this morning.
Things are running good and as expected.

Initially I posted there was gear slippage when shifting around 40-50mph
Maybe w/ the ATF drain and fills I did as well as the Dr. Transmission (I think it is) stuff, that seems to have taken care of things.

Have a 5 hour road trip coming up this weekend, so I will see how it does.
But after a lot of needed maintenance and repairs done, things are doing good.

I think the next upcoming maintenance will be belts getting replaced.

Ended up being a cut cable in the transmission harness that plugs in underneath..carefully tripple check the harness again, while trying to unplug it..and found 1 cable cut. guess it was being held up by tiny strands which finally parted.

truck still drives ok . same error code as before...only issue comes up when trying to accelerate from 40mph to 60mph...unresponsive, till i let up on the gas and try slowly again., changing that harness will be a pita :gun5:

Since you found the broken wire, is there any way you could splice a piece in there to repair it? I mean, the end result can't be any worse than what's happening now.

Check out The Car Care Nut on YouTube.He's a Toyota Master Technician he has some awesome videos.He made one on transmission's you should watch before you decide what to do.

so bit the bullet and cut the slot inside the cabin..stuck a pin inside the cut connection, glued it and joined the cut cable to it. the persistent p09xxx error code went away and i got 2 new ones p0713 and p0748 am thinking my continued driving of the truck with the initial error code may have made the fluid dirty. so i intend to drain and refill and refill the fluid and see how it goes. will buy a new harness if am able to get the Tranny MIL stay off
open to any other suggestions.

Edit: drained and refilled the tranny fluid but p0748 and P0713 MIL still persists. am thinking perhaps the solenoid is bad. who knows the exact solenoid responsible for p0748? [MENTION=66389]BlackWorksInc[/MENTION] , could you chime in here please.
