need some questions answered bout towing

i drive a 1987 toyota pickup auto 4cylinder. it has an ect normal or power button on it. for one what does ect do? also, if im towing in 4wd low, should i leave the ect button on power or normal?

 

IIRC, that changes the transmission's shift points. Power=higher rev before shift and quicker downshift with less accel input. Normal= lower rev before shift and more accel input before downshift.
Personal preference is the call of the day for that setting in 4lo.

 

Towing in 4 low? Not on asphalt I hope....

 

if u have something heavy to tow u can tow it in 4low to keep the strain off the transmission

 

ONLY use 4Lo to get it out of the water and up the ramp. DO NOT turn the wheels and drive on dry pavement in 4LO, you run the risk of binding the drivetrain and grenading your T-case.

 

Uh , no

See possible results, although I do not know what caused this one or what type TC it is, just a "broken transfercase" off google images:

An "87" has manual lock hubs you can drive all you want in 4X4 as long as the hubs are not locked don't think I would take it out on the highway. Either normal or power you'll probably not notice the difference in low. What you do want is an transmission cooler in line with the stock one.
