How do you know it is getting hot?

If so,your done,it will be ruined by now

Maybe the fluid was never changed since it
left the factory new & it can no longer remove any heat
& destroyed it's self

Some antifreeze is red, oil floats so stick your finger in the radiator fill while cold and if it feels oily there's your answer, but more commonly the seals in the clutch pack are going south, as the transmission heats up the oil thins out allowing more oil to pass by the seals, and the drop in hydraulic pressure makes it so the clutch pack cannot fully engage. you could try a can transX or other mechanic in a can to swell the seals but it's just a band aid and doesn't always work,you may want to change the filter also, as now you need to get rid of the extra oil you put in + the can of band aid, so it may not warrant a transmission rebuild if you know what I mean, might not even warrant the price of the filter and fluid, but that's up to you.

Transmission stalls after it gets hot


This usually happens when the transmission fluid gets hot.

Transmission fluid gets hot when there's not much of it.

Check your transmission fluid levels.

If it's low, you can fill it by pouring fluid down the testing hose. Just make sure to get a funnel.

Transmission slips after engine warms up


It isn't when the engine gets hot, it is when the transmission fluid gets hot that the slipping starts, due to wear of the clutches and gears inside the transmission.
First, check the fluid level to make sure it is full. If it is low, bring fluid level to full and see if that helps.
About all the owner can do with slipping automatics is trying a transmission fluid and filter change to see if transmission revives and stops slipping. The bottom pan is removed, fluid (about 6-8 quarts) is drained, and a new filter is installed before the pan is replaced with a new gasket, sealed up, and fresh fluid added. Sometimes it helps. Sometimes the transmission is worn too bad to help, and you are left with looking for a replacement transmission.
Check the fluid level first. Good luck.

Do you check the transmission oil level with the engine running with it in Park, or with the engine turned off (after getting the transmission up to normal operating temperature)?


The transmission will have a hot and a cold mark, it is best to run the transmission hot and check the oil level whilst idling in park.

I have a Volvo P0700 code , P0740 code. when the transmission is cold it works ok, when it gets hot it shifts hard and will lock in a gear/


OK allot of people don't under stand transmission because they think a transmission is complicated.
When the fluid is cold it is thick and can't move as fast and can't build pressure as fast as hot transmission fluid. There are small 1/16 holes in the Valve Body that the fluid has to pass through and Valve that get ***** out from allot of use. When a valve ware and fluid can go through the space that it couldn't before when it was new and the differences of hot and cold fluid makes a big differences. The fluid can move passed the valve and into the accumulators that operate the shift mechanism. So that why it shifts good when it's cold and hard when it's hot. Might be a sticky valve or shift solenoid or just need rebuilt. In the past if i had trouble like this and had to rebuild the transmission before i did that i would put a can of thick STP motor oil Treatment in the transmission because it thickens up the transmission fluid and make my car shift like new. Its not going to hurt nothing it mixes well with the transmission oil.

Transmission getting hot


If it's truly getting hot, then you have an issue with the cooler. Most circulate fluid through a coil inside one of the radiator tanks to cool the fluid. Some utilize an external cooler, usually mounted in front of the radiator. If you pull heavy loads, such as trailering, then you really need to install an external cooler. High temp oxidizes the fluid. For every 10deg rise in temp above 170deg the life of the transmission is cut in half. An external cooler isn't too expensive and can save you tons of $$$ in the long run.

My 1999 Z71 shifts hard on occasions. Seem to be after the transmission gets hot. Any ideas?


This only happens when the transmission is going bad wherein when it gets hot it does not shift easily.

Replace the transmission please.

Transmission won't go into overdrive when engine is hot


Lexus's have a complicated system of electronics that control the function of the transmission.Under normal operating conditions the transmission is controlled by the ecu and by a secondary system called a drivetrain control module. usually when a fault occurs it sends a code to the ecu and the check engine light comes on.
If this light does not come on then typically the electronic modulator is at fault and needs to be replaced.
If the check engine light comes on when the vehicle is hot i need this code to guide u further for the repair.
If u want to attempt the repair , be wary. its messy and takes time to do to do it right.
