How does an automatic transmission disengage in a car?
How does an automatic transmission disengage in a car?
When the engine is at idle there is less pressure trying to turn the transmission side of the torque converter, so you are able to hold the vehicle stationary with the brakes. If it disengaged every time you stopped it would eventually damage the transmission. It would be like shifting from neutral to drive manually every time you stopped.
What happens if you disengage the transmission at idle?
It doesn’t. Even at idle your engine can still creep the car forward (or backward). When the engine is at idle there is less pressure trying to turn the transmission side of the torque converter, so you are able to hold the vehicle stationary with the brakes. If it disengaged every time you stopped it would eventually damage the transmission.
How are the cooling lines attached to the transmission?
The trite saying “think outside the box” is apt when discussing automatic transmission cooler lines. For our discussion simply know that two cooling tubes are attached to the transmission, the hot and cold lines mentioned earlier. One component inside that “box” is a small pump that circulates the transmission fluid.
Why do transmission lines need to be replaced?
Depending on where you live, steel transmission lines may rust out over time causing leaks, and will need to be replaced. Depending on your vehicle, these may be very straight forward to replace, or can be a pain due to the space and the bends in the lines.
How do you remove transmission from cross member?
With the weight of the transmission resting on the jack, remove the transmission mount bolts. Removing the transmission mount bolts (or nuts) allows the transmission to be separated from the cross member. Remove the cross member to frame mounting bolts and then remove the cross member.
What can I do to prolong my transmission life?
Transmission Coolers, Lines, and Fittings. Transmission coolers are a simple solution to help prolong transmission life. Transmission heat is the prime reason for tranny failure. High performance applications like towing and high torque engines can build heat in the transmission and break down fluids.
How do you remove the transmission from a car?
Position your hydraulic jack (or transmission jack if you have one) under the transmission pan and raise slightly. With the weight of the transmission resting on the jack, remove the transmission mount bolts. Removing the transmission mount bolts (or nuts) allows the transmission to be separated from the cross member.
