'04 Prerunner Transmission Hesitation

95000 miles on it. Just changed my brakes, air filter and fuel filter. About 2000 miles ago it started hesitating in low gear. When it needs to drop a gear to pick up speed it delays for a couple seconds. This could cause a problem when I turn into traffic from a dead stop and need speed. Now before I ask any questions I will say that I have never changed my tranny oil or filter. (Shame on me) I know that is probably the cause of the problem and I'm going to change it soon. Regardless I wanted to know if there may be any other reasons for this problem. I.E. Spark Plugs, Computer, etc. Or if anyone else is experiencing this. Any help would be appreciated. Thanks.

 

welcome to tw.

you said it..............and i'll tell you its a clogged tranny filter. when you drop the pan...pull the filter out and clean with brake cleaner and replace....basically just a screen filter. it will take 4 to 5 quarts of t4 fluid for a refill. for the gasket on the pan.....just use some hi-temp rtv silicone.

 

I'm having the same issue but on my 2006 4WD 4door V6 (4.0 L) Auto Taco. I changed the oil last night (I'm at 48,800 or something like that), filled her up with 5.5 quarts of 5W-30 valvoline synthetic (i have run synthetic oil through the vehicle before- probably half the time- it was on sale) and dropped in a new oil filter. the only thing i can think of are maybe i knocked loose a vacuum hose? everything looked like it was connected this morning.

the truck reved up high before it would shift and didn't want to drop back to the usual running rpm range on the highway that it normally runs at.

 

how do you know it's even a tranny issue?

 

may need to get the dealer to check the tranny fluid. the 06 i had was a quart low from the factory and would late shift like hell.

 

My truck wont shift out of 2nd when it hasnt had time to warm up. I can slowly creep to up to 40 and the engine will scream its head off. Even when I let off the gas, it wont shift gears (ECT set to normal). Now when it warms up, it shifts just fine.

 

Mines been doing that for 9 years

 

^ Hmm... It runs great and is very smooth. Maybe its an ECT issue... Glad im not the only one though.

 

Hello, my 2008 did the same thing and I thought it needed the 09 tranny tsb but come to find out it was low on tranny fluid from the factory....
