tundra transmission issue

transmission shifts and works fine, but can only start from stop if shifting into low and manually shifting up to higher gears. Then after a stop, will only start out again if shifting down back to low to start from stop.
i would welcome any diagnosis.

The transmission otherwise shifts normally at all speeds except wont start out from a stop without first shifting into low.
when attempting to start out in drive it acts as it it is in N and does nothing!

 

I would try and post in the "1st Gen" section since it appears you have a 2001 tundra.

You are currently in the 2nd gen section.

 

What transmission is in this? It sounds like it has a mechanical governor and/or the tail shaft speed sensor is not working?

It should have some codes stored for this type of failure. Have you hooked up to it to read them?

Start there!

 

@T-Rex266 can we get this moved into 1st gen territory

 

Whats the fluid look like? I'd lean to a burnt clutch pack if the fluid was recently changed. But maybe a stuck ball.



If it was a solenoid, it would try to jump into 3rd when you put it in drive.

any codes?

 

Did you check the fluid level? Failure to automatically shift properly is a classic symptom of improper fluid level.

I doubt that's what it is, but it's the first thing to check any time you're seeing trans probs: Is the fluid the right color? Is the fluid level proper?
