Toyota Tacoma Transmission Problems

My 1995 Tacoma has 122,000 miles. About 8 weeks ago, I began having trouble with first gear. Basically, when I was starting out from a stopped position (like a stop sign), first gear would slip out of gear and the truck would make a loud noise while jerking once violently. This occurred about once a week for 3 weeks. In the 4th week this problem began to occur very frequently and happened at every other stop sign. This first gear problem stopped when I decided to hold first gear in gear with my hand while driving. In other words, first gear was fine as long as I applied pressure to the gear stick while it was in gear. In the 5th week, third gear began acting up. Basically, when shifting to third, the gearbox would grind loudly and kick the gear stick out of gear. It felt as if the gear box was refusing to accept third gear. The following week (week 6) first gear was fine but I could not shift into third gear. The gear box refused to accept third gear. In response, I bypassed third gear for 2 weeks and shifted from second gear to fourth gear without any problems. At this point all of my gears were working fine except for third gear. In week 8 (which was 3 days ago) while carrying a heavy load in my truck bed, I decided to try out third gear once again. This time third gear worked fine. I have been using third gear for 3 days now and it feels fine except for one thing: it still does not feel like it is completely locking into gear. In other words, it feels a little spongy. Currently, I am driving my Tacoma with all 5 gears plus reverse. They are all working fine for now, but I am puzzled about this gear box issue. Any help would be greatly appreciated

Over time, I have to press the clutch pedal to the floor for the engine to start. It's not the clutch, the clutch is working fine once the engine's running. There has to be a safety switch - Where is this switch? and is it adjustable? ManN

I took my truck to Toyota and they checked my transmission during a "cold start" and they said the electronics tested ok. I posted a message at http://www.tacomaterritory.com/forum/showthread.php?t=124719 and this is one response I received: "As for the slipping you mention... I doubt it. The transmission in this truck is controlled by the computer. It doesn't have vacuum modulators or governors like the old school stuff you are used to. What happens is that you tell the computer what you want, and it tries to figure out the best way to do it. It does this by keeping a record of what you have done in the past, and what turned out to be the best response to your input. The computer in this truck controls throttle opening, fuel delivery, spark advance, cam timing, gear position, and just about every thing else that makes the truck go. If you are not smooth and predictable with your input to the computer, you can confuse it. it's trying to keep up with your requests, but it has to change it's response because you changed your input. Try being smooth with the gas pedal (It's not a gas pedal, it's only hooked to the computer) and let the computer learn your habits. it will get better about responding to your driving style quickly. Yes, the truck downshifts when you are slowing down, and yes you can feel it. Sorry your nissan didn't do that, but the old school nissan tranny's faults don't mean the Toyota has a problem. After a while you and the truck will get used to each other and things will be fine. That "Fly by wire" system in your Tacoma is an amazing thing. When you get the hang of operating it, you will love it." I am saving every documented instance of this to a folder, in case I need to show proof to Toyota some day that other are having the same problem. |
