Can I drive with a transmission problem?

If your Toyota Tundra can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.

How often does a Toyota Tundra transmission need to be replaced?

The overall lifespan of a Toyota Tundra transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Toyota Tundra transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.

How are Toyota Tundra transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Toyota Tundra transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.

How is a Toyota Tundra transmission replaced?

In order to replace your Toyota Tundra transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed.

How to Solve Toyota Tundra Transmission Problems

Solution A: Buy a Used Toyota Tundra Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.

Solution B: Buy a Rebuilt Toyota Tundra Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.

Solution C: Buy a Remanufactured Toyota Tundra Transmission

Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

Mu 2007 was fine an then only reverse would work. Any suggestions. The factory trans was rebuilt T 75000 and at 123000 it only works in reverse. Help!!!!!

Kevin C

2002 Tundra, A340E, 330,000 miles, no issues ever, have done a full transmission flush ever 35k miles, want to start pulling a boat, < 2500 lbs, some long trips , 500 miles, maybe 3 times a year. Have been running full synthetic for the last 3 or 4 flushes, I realize my transmission may not be the norm, but is the A340E Transmission a reliable one on average? My Tundra came from the factory with a tran cooler. I will install a team gauge, where do recommend I put the sensor? Should I get a rebuild because of the miles, or wIt to see if any issues occur with high temp? Any observations or guidance would be appreciated? Thanks!

Randy L Kile

I have a 2014 tundra it shifts good until I drive it about 20 miles then it won’t shift from fourth then I can let it set for a while then it’s ok again what do I need to do

Grzegorz Nysk

Randy, I have the same issue…Did you have your problem resolved? What was the problem?

Brian D

i have a 2008 Toyota Tundra with 65000 miles from new ,, After only 800 miles on it i had to have the torque converter replace under warranty . Since then the transmission has acted up Every now and then the trans slips when pulling away from a stop position . It is very intermittent .could go a day or a month before doing it again i have taken it back to the dealer several times They could not find a problem
All they told me was its under warranty if it go’s out we will take care of it I bought extra warranty when the factory warranty expired to cover the trans and running gear Thank god i did.. Since then the the rear wheel bearings.. front diff.. water pump has gone out [[[[ secondary air valves filled with water and was replaced under toyotas warranty]]]]
2/19/19 took it back to the dealer again doing the same thing trans acting up ..They test drove it but could not get it to do it They know that there is a prodlem with this as they have asked me several questions that relate to my trans It tells me that they have run across this before but are very reluctent to do any thing about it, Still covered till OCT 19 Has anyone esle came across this problem PS the bed is also rotting though at the four anchor points

Debbie

I have the 2007 with 80 thousand miles , with the exact same issues. They replaced the transmission because I have some platinum million mile warranty. That was 6 months ago. It’s back at the dealership now with the same issues. Only had 3 thousand miles on this transmission. They are replacing it again (still under warranty) but I know it’s not going to fix the issues. Now all my electrical things are acting wonky

Trans locked in park

2007 Toyota tundra crew max as long as I let my truck run a good 30 min every thing is ok. But if i start it up and try to leave before then it either barely moves or do a lot of jerking until it warms up very frustrating. What if need to leave in a emergency not gonna happen has a 167000 miles on it

p.E.Wall

petter dybesland

hi, i have a 2007 mod tundra 5.7 ltr with apr 200000 miles on it and gear no 6 doesn’t come in, test says solenoid prob. where to locate the solenoid , change it or …?

Travis B

I have the same year truck with the same problem. I just had the dealer flush my transmission the other day and immediately afterwards it won’t shift smoothly between gears 2 and 3. Dealer said error relates to a solenoid and that I need a new transmission but I’m still in discussion with them on an alternate solution as it was functioning just fine until they flushed the tranny.

Randy

Don’t ever let them flush the tranny. Change fluid through the tranny cooler lines by pinning open the cooler thermostat. Flushing the tranny forces metal shavings and gunk into the little channels in the body causing your tranny to no longer work right.

Dale M.

My 2007 Tundra with 180,000 miles, is doing the same thing, about 3 weeks after having the tranny flushed(by a long time toyota mechanic)….Tranmisson guy says $1000 to $3400 to fix it. Should I trade it in or try to fix it.

Jacob

Should try to fix it. these trucks are ment to last years., i just recently bought a 2011 Tundra with 170,000 miles on it and runs smoothly. But before that a 2004 Pontiac Grand am GT and had a torque Converter solenoid go out and had it rebuilt for 2500 with a 2 year 25,000 warranty and ran smoothly and good till i wrecked it. so yes do not flush it can cause issues from then on just go to a good transmission shop and get their opinion, but will say they cannot guarantee it because it is a transmission and may break.
