Can having your engine seize cause transmission problems too?
We bought a used car from a reputable Honda dealership and 10 months later we found out that they had actually purchased the car at auction a few months before we bought it and knew that the engine had seized previously and just kind of been patched. So then the engine completely goes out on us and needs to be replaced and now they're telling us after they replaced the engine and ran the car 100 miles they had to also replace the transmission completely. Is this normal? What other problems can we now expect? We kept up with every maintenance before the car broke. We are good car owners. It
Experienced mechanics share their insights in answering this question :
If your vehicle has an automatic transmission, the engine drives the transmission through a fluid coupling known as a "torque converter". As a consequence of this design, if the engine were to suddenly stop, the transmission (and differential) would continue turning and there is little likelihood of damage. Any mechanical component in a vehicle can fail and the probability of failure will increase if the vehicle was previously damaged, abused, or not maintained. As far as predictions of what additional components on the car can or will fail, such can only be determined if the vehicle is thoroughly inspected, and in the case of some components cannot be predicted at all, for some parts and assemblies that cannot be readily disassembled. Buying a used vehicle does have significant risks associated with it. To protect yourself in any used car transaction, YourMechanic recommends that a pre-purchase vehicle inspection be performed. That inspection, carried out by a certified Mechanic, dispatched to your location by YourMechanic, will give you very specific data regarding any current problems with the actual car you want to buy. Even though you already own the car, you can still request an inspection in order to determine if there are going to be any obvious problems going forward. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.

Shifts are delayed or missing gears
Other possibilities could be an engine related problem that will cause the computer to not allow the transmission to shift into higher gears.
When the transmission has actually gone out, basically your vehicle will not move. This is because the gears can no longer get power from the engine. As a result, the engine will idle, stall, or surge when shifting gears.
If the torque converter fails to unlock when the vehicle slows, the engine would stall as the the vehicle stopped. The most likely cause of such a scenario would be electronic in nature. The engine wouldn`t actually be “locked up”, it would just be locked to a gear set that wasn`t turning, as the vehicle is stopped.
Seized car engine symptoms:
Fumes/smoke: since the engine can`t turn over, fumes, smoke, and even fire can happen – all of which are a sure sign of an engine seizure. Nothing: the most tell-tale sign of a seized engine is when nothing happens. When your car won`t start no matter how hard you try.
On one hand, an engine halts when it gets seizes, which usually happens. Otherwise, it may be locked up. However, there are a whole lot of different reasons for an engine seizure or lockup. A locked up engine and complete seizure do not allow a vehicle to move.
Transmission Range Sensor (TR)/ Transmission Position Sensor
The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
Your transmission is a part of the engine that transforms power into torque. Torque is a force that rotates an object—like a wheel—around an axis or axle. Your transmission turns all of the motion in your engine into something that gets and keeps your car moving.
Parts are not properly lubricated, there is an increase in friction, and the transmission will damage itself and eventually seize up, which often results in a prohibitively expensive repair. This problem is often caused by using sub-par transmission fluid or because of a low fluid levels.

Engine seizure is caused by overheating or lack of lubrication. Without oil, the engine`s moving parts will no longer move smoothly against each other, and the engine will overheat. The first symptom may be a loss of engine power. You may also notice a change in the engine`s sound.

Kia Optima 2004 v6 LX new engine old transmission no problems before with transmission now my transmission is shifting a high rpm
ANSWER : Hi There,
This may be an issue related to the communication of the PCM and the TCM (Transmission control module). As you may know, the TCM relies on the PCM to transmit information related to RPM’s, which the TCM then uses to determine when to direct the transmission to shift. The transmission control module has various sensors such as vehicle speed sensors, wheel speed sensors, throttle position sensors, turbine speed sensor, and transmission fluid temperature sensors that all direct information to it in order for it to perform it’s function. Other functions controlled by the TCM are components such as a kick down switch, traction control system, and cruise control module. Any of these may also affect the way the transmission control module performs and controls the transmission and the shifting of your vehicle. I would suggest having a professional from Your Mechanic come to your location to properly diagnose your transmission problem.

Seized engine, no oil leaks
ANSWER : Did your oil leak out from somewhere? Did your drain plug fall out? Did your engine have a major engine failure? I suspect the drain plug fell out on your engine. There have been incidents of the oil pan getting cracked around the drain plug hole causing an oil leak. This would be a slower leak. If drain plug was not tightened up and vibrated until it fell out, there would have been a large sudden leak with all oil being lost and causing the engine to seize pretty fast. Did you just have a recent oil change? I have seen owners that have had their oil changed and lost all oil in a short time because of the oil plug falling out from not being tightened properly. I would suggest you have YourMechanic do a thorough diagnosis of why you lost all your oil. This should give you some insight why oil was lost.

TCM causes engine light to come on, but no transmission problems – is it safe to drive it?
ANSWER : The first thing I would do is scan the vehicle for codes to determine if the TCM is still the issue. If codes for the TCM appear, depending on the code and the problem, you may be fine to drive that away. There is no way of telling how long the transmission will last, so it is a gamble to have the other repairs done. I would certainly get the brakes done as this is a safety issue, and get roadside assistance in case your vehicle’s transmission decides to fail unexpectedly. If you would like to have this all checked, a professional from YourMechanic can come to your location to inspect the car for you and recommend the correct actions.

Stalling engine, brakes, power steering and transmission failure
ANSWER : The stalling may well be caused by a failure of the crankshaft position sensor. This device provides timing instructions for the ignition system. When it fails, the engine no longer gets spark at the spark plugs and stalls. When the car stalls out, the brakes and steering cutting off are typical symptoms that go along with the car shutting off. To have all of this scoped out, a certified professional from YourMechanic can inspect your car for a correct diagnosis of the stalling issue.

I was already having transmission problems. Will constant use of Cruise Control further deteriorate it? Will it cause CC problems?
ANSWER : Hi, thanks for writing in. The cruise control uses some of the same sensor inputs the transmission uses and can indeed affect the transmission and cruise control. If the transmission is slipping then the cruise control may not control the speed steady. Have the transmission problem diagnosed and fixed then see if cruise control problems go away.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

Can too much transmission fluid cause speedometer malfunctions?
ANSWER : Hi there. In most cases when you overfill the transmission fluid it can cause excessive foaming of the fluid or possible internal component failure due to excessive pressure inside the hydraulic lines. Sensors like the speed sensors however are rarely impacted by this situation. However, in regards to the possibility of probability of this; I would say perhaps a 10% chance.
