hi i have a 2001 toyota tacoma and just recently when i start it up in the morning when i go to drive off it wont go its very sluggish maybe 4-5 mph no matter how much i step on the gas pedal but it will go in reverse just fine in order to get it to drive i have to let it warm up all the way its never acted like this before can someone please help

 

Thermostat?

 

Ok once the truck warms up does it drive fine? Do you let your truck warm up at all when you first start it up? Where do you live (how cold is it in the mornings)? Let's start there.

And welcome to YotaTech!

 

Sounds like a valve body(trans) problem to me.......let us know if figure it out.

 

My 99 4runner is doing this exact thing. I let it warm up for a good couple of minutes and reverse acts fine out of the driveway. When I put it in D, it barely goes for about 20 - 30 seconds, then slowly starts gaining speed and then its fine. Doesnt feel like its out of gear, it doesnt suddenly jolt forward, just real slow going, but the RPMs increase with more gas, but no go.

Any suggestions ???

 

How many miles on your 4Runner and when was the last transmission fluid change/flush?

Mugatu!

 

125K miles. Dont think thats been done. Could that be the problem ???

 

Yeah, that has been waaaaaay over due. Check your transmission fluid. Hopefully, the damage isn't permenant. Do a flush.
