2007 Tacoma Transmission Issues

Hello all, I am having issues with my automatic transmission where there seems to be a delay in shifting sometimes. I will give you a few scenarios if anyone can shed some light on the issue.

Going from Park into Reverse, or Reverse into Drive, or Drive into Reverse: There is a significant delay where it feels like it will sit in neutral and after I rev up a little it jerks into gear.

Another scenario: I slammed on the brakes and then got back on the gas and it again went in a neutral state and then jerked hard into gear.

Also: Rolling stops. If I don't come to a complete stop it feels like it does the neutral thing again.

Truck Info: 2007 Tacoma 4.0l V6 TRD Off-Road 4x4. It was having these issues, I did an transmission oil change and didn't seem to make much of a difference. Now I am stumped.

 

That sucks. Have yo tried resetting the computer? Disconnect battery for about 30 minutes. Beyond that, you may have to take it to a tranny shop. Looks like internal seals are malfunctioning.

Sounds like someone didn't follow Toyota's recommendation for maintenance, don't know what they say for your '07, 1st gens with the A340F are a drain & fill every 30-35k., not to be confused with a flush & fill which is what I think yours is if it's a sealed unit ( no visible dipstick for checking fluid )These have to be evacuated , including torque converter, but anyway you better start thinking about a trans & have a fat wallet...Went thru this with my 1st gen.

 

Here is a couple possibilities.
Low fluid level
Torque converter going bad

 

How many miles?

When last serviced before this recent change?

Was your change a drain and fill or flush and fill?

 

It has around 130k miles. I just bought it in August and it wouldn't surprise me if the previous didn't follow the recommended service schedule. I just did a drain and fill when I did the oil change. It is a closed system.

 

From reading these articles I am fairly certain it is the seals that are wearing out. I really doubt the previous owner ever did an oil change on the tranny.

Wow this is exactly what I needed. I am pretty sure is it a low fluid problem, considering the way I filled it myself. Also flipping toyota dealer gave me the WRONG fluid! Looks like I have an afternoon project. Thank guys!

UPDATE: So right fluid, and enough of it, fixed my issues. Shifts like a champ now. Thanks everyone for their input!

 

Hey guys! I have the same issues with the same year Taco. TRD. Check engine light is on, same funky jerky and inability to shift properly. I know it has a sealed transmission and as far as I can see, it isn't leaking. The last thing I want is to get ripped off by a dealer. Should I just reset the battery? Or is it time I faced the music and take it in?

 

If your having trans. issues you need to know that rebuilding yours is going to be around $3400+ if not maintenanced properly soon..

 

Take it to a trusted mechanic. I avoid dealers unless I have an issue that can only be fixed by them such as a computer problem. I just feel like they aren't worth the hassle and lies, but that's just me. Take it to whoever you think will give you the best answer.
I would also take it in ASAP. Don't mess with transmission issues.

 

If you want to save some time/money, check the fluid level first. That fixed all of my issues.

 

How do you check fluid in a sealed transmission ?

I agree

I would like to hear why that check engine light is on . Considering you have a computer controlled transmission , Having a scan performed as well as checking the fluid levels as mentioned above would be a great place to start

 

I am having problems with my transmission now. Stopped at a red light yesterday, and when the light turned green my truck wouldn't go anywhere. Any suggestions

 

Take it to a trusted shop for a full fluid exchange with Toyota WS- or dealer if reasonable.
