Car Forum / Toyota / Toyota Cars / January 2008PU Auto trans question
1995 Toyota Pickup, extended cab, only 56000 miles 4 cylinder with automatic overdrive transmission In the morning I have to drive 4 to 6 miles before it will shift to overdrive. Is this a problem or just idiosyncratic of the transmission? After it warms up a bit no problem.

I don't know why, but Toyota (and a lot of Japanese ATs) keep the tranny from shifting into OD until the engine reaches a certain temperature. I had a '95 Tercel, and it was noted in the, uh...Owner's Manual. If you have one, take a look and it should be in there... >> 1995 Toyota Pickup, extended cab, only 56000 miles 4 cylinder with >> automatic overdrive transmission [quoted text clipped - 10 lines] > I had a '95 Tercel, and it was noted in the, uh...Owner's Manual. If you > have one, take a look and it should be in there... Under about 50 degrees, my Tacoma won't shift out of 3rd gear until it's warm. Under 30 degrees, it won't shift out of 2nd. It takes a minute or two. Luckily, it takes me that long to get out of my 25 mph neighborhood and onto a street where going that slow would be a problem. >> I had a '95 Tercel, and it was noted in the, uh...Owner's Manual.

Maybe it has something to do with engine size. My Tercel had a 4 speed AT with OD and lock-up, and would stay in third until the temp guage read about 1/3 operating temp. >>> I had a '95 Tercel, and it was noted in the, uh...Owner's Manual.

[quoted text clipped - 9 lines] > speed AT with OD and lock-up, and would stay in third until the temp guage > read about 1/3 operating temp. This is a 6 cylinder. From discussions in the Toyota truck NG, it's apparently normal, and a bit unnerving. If it's ridiculously cold, I'll drive around the neighborhood for an extra couple of minutes. No way I'd get on a highway with that happening. >>>> I had a '95 Tercel, and it was noted in the, uh...Owner's Manual. If >>>> you [quoted text clipped - 16 lines] > drive around the neighborhood for an extra couple of minutes. No way I'd > get on a highway with that happening. As I mentioned before, the delay in shifting into OD is designed to reduce emissions. There is no reason to drive around and stay off the highway until it shifts into OD, and you are just wasting fuel. Way back in the olden days before OD was common, people drove on highways all the time without any problems. It would be better for fuel economy and the environment if you just drove it normally.

Just to be sure we agree, the minimum speed on the highway in question is 45 mph. > >>>>> I had a '95 Tercel, and it was noted in the, uh...Owner's Manual.

Just > to be sure we agree, the minimum speed on the highway in question is 45 mph. I would imagine in this case, the answer would be NO. You're a danger to yourself and others when you go slower than the designated speed and in most states, that's grounds for getting a ticket. >> >>>>> I had a '95 Tercel, and it was noted in the, uh...Owner's Manual. >> >>>>> If [quoted text clipped - 43 lines] > to yourself and others when you go slower than the designated speed > and in most states, that's grounds for getting a ticket. That is the correct response. Thank you. Judge, I got no foither use for this witness. Bailiff, give the witness a free six pack of his choice from the cooler. >>> >>>>> I had a '95 Tercel, and it was noted in the, uh...Owner's Manual. >>> >>>>> If [quoted text clipped - 49 lines] > this witness. Bailiff, give the witness a free six pack of his choice from > the cooler. The correct answer tothat question is, it depends. I own a Mazda MPV, and while driving on the freeway near my home, and getting further and further away, the transmission downshifted for no apparent reason, and remained engaged in the resulting gear -- that turned out to be 2nd -- and I had absolutely no trouble maintaining 45MPH. The question that ran through my mind was the ramifications of the problem betting worse before I got to where I was going. Since I was on a mission that I could not abort, I kept going to my destination, then called the auto club to come get me. It turned out the transmission had stripped some serious gears somewhere inside, and I was forced to get it rebuilt. If the car can maintain the minimum speed without danger of screaming to a sudden halt in traffic lanes ... How does one know, that is the question. >>>> >>>>> I had a '95 Tercel, and it was noted in the, uh...Owner's Manual. >>>> >>>>> If [quoted text clipped - 70 lines] > > How does one know, that is the question. What you described is different because it was unexpected. If you KNEW the car could not get out of second gear, and if you KNEW that doing a safe minimum speed in 2nd would cause the engine to rev higher than you think is a good idea, you would not get on a highway under those circumstances. There are people who DO get on fast-moving highways and flop mindlessly into the right lane doing 37 mph. Those drivers are called names that shouldn't be repeated in front of children. These drivers are defective. There's no good reason to emulate their bad behavior. >> The correct answer tothat question is, it depends. >> [quoted text clipped - 25 lines] > shouldn't be repeated in front of children. These drivers are defective. > There's no good reason to emulate their bad behavior. Had I realized what had happened to my MPV, I'd have parked it differently and then I could have driven it home again, and avoided a trip on the flatbed. So, my issue was not the speed it can go in 2nd (it easily went faster than 45), my issue was if it was going to make it back to the house without failing entirely. Engine speed is an issue, sure. But 2nd does not preclude conditions that the engine can not keep up with. There are vehicles that can't do 45 in 2nd for veery long, but there are vehicles that can do 45 all day in 2nd and live to tell the story to the grand kids. <snipped> >> This is a 6 cylinder.

If it's ridiculously cold, I'll [quoted text clipped - 10 lines] > Just to be sure we agree, the minimum speed on the highway in question is > 45 mph. I probably would get on a highway with a minimum speed of 45 MPH in a vehicle that won't leave 2nd gear as long as the 2nd gear ratio is such that the engine isn't over redline at whatever speed I'm driving. The question is moot if your Toyota electronically controlled automatic transmission is functioning properly because it will upshift at redline regardless of coolant temperature. You may think you are in 2nd gear, but you are probably in 3rd with the torque converter unlocked.

One might think, but it really is an odd behavior that I've never seen in other cars. I've tried getting the truck up to about 40 mph when it's dead cold, and it still won't shift out of 2nd. RPMs are definitely high enough at that speed. >>>> <snipped> >>>> [quoted text clipped - 31 lines] > cold, and it still won't shift out of 2nd. RPMs are definitely high enough > at that speed. No, RPM's are not definitely high enough to shift out of second if it is dead cold out. Take the engine up to redline and describe what happens. SignatureRay O (correct punctuation to reply) >>>>> <snipped> >>>>> [quoted text clipped - 36 lines] > No, RPM's are not definitely high enough to shift out of second if it is > dead cold out. Take the engine up to redline and describe what happens. No. I won't do that. Doesn't feel like the right thing to do. I'd rather drive around slowly for an extra 60-120 seconds. Or, warm it up for 2-3 minutes, if (and only if) there's some snow & ice to scrape off the truck. <snipped> >> No, RPM's are not definitely high enough to shift out of second if it is >> dead cold out.

If you read my posts, you should know that I don't give advice that would cause permanent damage to your vehicle, but I understand and respect that you wouldn't feel comfortable bringing the engine up to redline and most people feel the same way, so I'll describe what happens at redline. "Redline" is the maximum speed and engine can operate without harming the engine, so up to and including redline, no harm to the engine. Toyota's engineers have taken environmental conditions into account when determining redline, and test vehicles are driven at Toyota's test facility in Arizona during the summer and up near the arctic circle in the winter. On a Toyota (and I assume all electronically fuel injected engines), the ECU governs engine RPM by cutting fuel by not opening the injectors at redline. Without fuel, the engine RPM will drop, and when sufficiently below redline, the ECU will deliver fuel again until the engine reaches redline, and the process continues until the operator backs off of the throttle. When this is happening, the vehicle's occupants will experience a jerking sensation, much like someone who is just learning how to use a clutch or an engine with a very severe engine miss. Of course, at 6,000 RPM or whatever redline is, the engine is making a pretty fair amount of noise. The transmission ECU will shift just under redline regardless of coolant temperature. In other words, even when it is cold out, you can start your engine and drive wherever you need to drive without worrying.

Ray, I appreciate the advice, but this is one of those rare instances where the facts don't matter to me. :-) I mean, I could also beat my son. He's big & tough, and he'd get better in a few days, but I don't do it. I'd rather argue with him. It's easier. <snipped> > Ray, I appreciate the advice, but this is one of those rare instances > where the facts don't matter to me. :-) I mean, I could also beat my > son.

This helps the engine warm up more quickly so that the engine computer will go to closed loop mode more quickly, lowering emissions.

As I have driven the truck more and more at 70 MPH, the transmission has loosened up. I think it may have been a little sticky because it is not driven at highway speeds often. It is my father in laws truck and he is 77 and does not drive much any more. He loaned it to me until I have time to fix my car....at 357,000 miles I am rebuilding the engine in my 1959 Lark VIII. 259cid with 3speed overdrive. Should be ready in about 6 weeks JIm in Republic of Texas |
