Transmission shifting issue

Hey everyone, searched a bunch and couldn't find any info, here's my problem: (2018 4x4 trd sport auto trans)

While truck is at a traffic light it, when I accelerate the truck revvs the engine, but 1 second later the gear comes in and just makes the truck go, but it feels terrible, like if it were in neutral and i would rev the engine the hit Drive, you can feel the gear going in very abruptly. does at as well while going on a steep uphill, if i leave the gas off for a second and then accelerate it will do the same, like revving the engine then the gear comes in.... gears are not spinning or making any noises, just this weird issue.. and it is not consistent, but it is there, any ideas or sugestions??

 

Mileage and service history on trans, if any?

 

Has your 2018 had the transmission TSB? See post #10 on this link for the TSB. Also have you checked you transmission fluid level?

I would for sure start with checking the level or honestly even at your age, if it hasn't already been done just change it all together and go from there.

 

I have noticed that 3rd generation Tacoma ATs will hesitate and “clunk” if you apply the accelerator while the truck is slowing but still moving. Especially going up a hill. It feels like the transmission is dropping down a gear to get moving. I avoid this by allowing vehicle to slow to a near stop before hitting the gas pedal. I have not noticed this clunk ever when accelerating after a complete stop such as at a traffic light. It might be a good idea to have your transmission checked. Hope it’s nothing serious.

 

When did this start?
What’s changed?

 

Bought the truck used so not sure on the history on trans, truck has 63K miles on it.

 

Started about 1 month ago, nothing changed, just started doing it... guess 1st change the oil and go from there

 

thanks for the link, bought the truck used so really don't know if that has been done, going to change the fluid 1st and go from there i guess...

 

Yeah, just gonna start with that and go from there.. hope that fixes the issue

 

A pain but probably worthwhile at this point. The TSB didn’t do much for me

oh boy, yeah, kinda figured 1st do that.. a pain for sure.. thanks

 

UPDATE: trans had only about 2qts in it (no leaks, nothing), so pretty confused on why it had that small amount of fluid in it, drained it, filled with new fluid, replaced filter.. trucks runs perfect now..
