What should the temperature be for an automatic transmission?
The ideal temperature for an automatic transmission is around 175 degrees. Cars do often have the coolant for the engine as a heat exchanger for the transmission fluid and therefore, they will often hold the same temperature if you are driving it normal. However, if your transmission is slipping a lot…
How to prevent automatic transmission damage when towing a trailer?
The vehicle would normally accelerate up to a safe speed but it can’t due to the trailer’s weight. Speed up in 2nd gear or slow down and get in 1st gear to prevent this. When in 3rd or 4th gear on the highway, the transmission may run hot reducing your fuel economy, but it shouldn’t cause damage.
What happens when the transmission temperature reaches 290?
The fluid varnish starts destroying the internal components of the engine like the valves. By the time the temperatures reach 250 degrees, the rubber seals have started cracking and leaking pressure and liquid. At over 290 degrees, the transmission will often have stopped working due to damaged parts and seals.
When does the torque converter lock up in a car?
On most vehicles this will allow torque converter lock up to occur in 3rd gear, which is now the highest gear. This can have a large impact on fuel economy, often over 25% improvement with the transmission now running cool. This simple rule is to keep RPMs up.
What’s the normal temp for transmission while towing?
200 is no problem towing. Like above 220 is getting too much. If the trans has never been serviced, you should do that. It would be a good idea to have synthtic fluid put in. It will tolerate more heat without breaking down. Posted By: overdrive75 on 02/17/12 06:42pm That temperature sounds right on the money for a 4L60E towing.

Can a 5 speed transmission overheat a trailer?
More modern 5 speed transmissions may be less susceptible to the 2nd gear overheating condition. The early to mid 90s Toyota Camry owner’s manual says to not drive continuously while pulling a trailer if the transmission is staying in 1st or 2nd gear, but it doesn’t say why.
When does transmission fluid overheat and damage occur?
Transmission fluid overheating and damage primarily occurs when the transmission is operating in 1st or 2nd gear. Overheating can occur in 1st gear when going slowly up a steep hill, for instance when you are stuck in traffic that is creeping along at only 5 MPH.
What to do if your ZD30 Turbo goes over 20psi?
If you are noticing boost pressure spikes over 20psi (up to 25psi is not uncommon), fit a boost limiting device such as a Dawes valve. These can be set so that the turbo can’t boost over say 18psi.
How to help your Nissan Patrol ZD30 turbo engine?
Take the car for a long drive 1-2 hours at least once a month to help clean some of the carbon out, also a fuel system cleaner will help this process by adding one every four fills. Heres a link to our ceramic and billet Nissan Patrol Turbochargers: Need the Turbo? Call us on 0385553989
What kind of compression ratio does Nissan RD28 have?
The RD28 has a cast-iron cylinder block, an aluminum cylinder head with SOHC (Single overhead camshaft) and two valves per cylinder. The Nissan RD28 compression ratio is 21.2:1.
How big is the intake valve on a Nissan RD28?
Intake valves are 39.0 mm (1.54) in diameter, and the exhaust valves are 32.0 mm (1.26 in). The early Nissan RD28 engines were equipped with valve shims for adjusting the valve clearance, the later versions used self-adjusting hydraulic tappets.
