What is the torque spec on the oil pan bolts?
Engine oil pan bolts range in torque from seven foot-pounds to 22 ft-lb or more for large engines with heavier pans and bolts. Once you’ve torqued the bolts and filled the engine with oil, you should run the engine for five minutes to bring it up to normal operating temperature.
How tight should tranny pan bolts be?
Pan bolts should be 8mm, probably 20mm long. Start the two rear bolts by hand using your socket. Do not run the bolts up too tight. If you drain the torque you should have drained most of the fluid from it so you can add all the recommended amount but for maybe a quart.
Do you need a torque wrench for transmission pan?
We should always tighten transmission pan bolts to the specified torque, when we install them. This is done with a torque wrench. Over tightening the pan bolts will only damage the gasket or worse, strip the bolt threads.
How many pan bolts does a 4L60E have?
Early 1/2 ton 6.5T’s had the 700r4. Easiest way to tell is pan shape. 4L80E is shaped like a rectangle with two corners lopped off and 17 bolts. 700r4/4L60/4L60E is pretty much square with a couple irregularities and 16 bolts.
Do you hand tighten oil filters?
Every reputable oil filter is designed to seal for tens of thousands of miles with no more than a good hand-tightening. You don’t need a wrench unless you have one of those deeply recessed filters with no space around it for your hands. Then use the wrench to tighten a half-turn more.
How many bolts are in a transmission pan?
TH350 / TH400 Transmission Pan Bolt Set of 13 bolts Use these bolts to secure your transmission pan.
What is the torque on transmission pan?

Do I have a 4L60 or 4L80?
Appearance. The 4L80E can be told apart from the 4L60E by looking at their transmission fluid pan. This is because the 4L80E has a pan that is oval in shape whereas a rectangular pan is featured by the 4L60E. Specifically, there is a gasket of 17 bolts on the 4L80E, while the 4L60E’s pan has 16 bolts.
Is a 4L60E interchangeable with a 4L80E?
FYI – 4L60E & 4L80E transmissions are NOT directly interchangeable. The wiring pinout of the trans plug is different, and 2 VSS’s are used versus 1 on the 4L60E. Besides the wiring difference, the ECM also requires a segment swap as that portion of the transmission control is completely different.
Are all 4L60E transmissions the same?
4L60E transmission bellhousings are not the same. One of the main differences in the earlier and later 4L60E transmissions is the bellhousing area. In the earlier versions, the case was cast as on piece of aluminum. In the later versions of it had a removable bellhousing.
What are the dimensions of a 4L60E?
The 4L60E has a weight of 150 lbs without fluid and the length of 23.5″, while the 4L80e have the weight of 236 lbs and the length of 26.4″. Just with these number, you can probably calculate that there is a big difference in size and weight between these transmissions.
What is 4L60E transmission?
