4L60E question

i think the bottom port is the out, and top is in, correct ?

trans cooler, ports on the side, 1 top, other bottom. does it matter what trans port goes to cooler port ?

fluid leaves the trans from the pump, correct ? when it returns to the trans, where does it go ?

thanx

yes... bottom fitting = out ....


either port on cooler is fine. Cooling system of trans is under pressure... there should be no check valve in this cooling system.


Fluid leaves trans out of the converter... returns from cooler to the lube circuit of trans.

trans. cooler hook ups /

I (IMO) would connect the bottom trans line to the bottom cooler line, that way the fluid from the trans. would keep the cooler full at all time before returns to the trans. The other way if the pressure every got low, it may drop through the cooler allowing air in the system, and not cooling the fluid. It also gives the fluid more time to cool.
I'm also the guy that likes putting a bolt up from the bottom with the nut on top. That way if the nut comes off, the bolt will drop out, and should be seen sooner. The other way, the nut falls off, and it wobbles around egg shaping the hole, if you don't catch it. (JMO)

ok. the lube curcuit. does the cooled fluid augement the curcuit, or is the curcuit completely reliant on the cooler fluid ? or put another way. the cooler line gets pinched. assuming the trans is not hot, will it work fine (and no damage), until it overheats ?

what is the best cooler line size ? would putting larger make a good difference ? would putting smaller hurt anything ?(assuming the trans is not overheating)

thanx

i agree

i disagree. i put the bolt in from the top, nut on bottom. if the nut falls off, there is still something there to, at least try, to hold whatever its in. if the bolt falls out there is nothing holding whatever. this can be correctly argued either way.

It is a pressure fed cooling system, not open to get air into it.

It feeds the lube circuit... cut off lube the trans burns up... same process on an engine , cut off lube,, the engine burns up.

apologizes.... I did not answer the line size question.

Does your 4L60E have clip in lines or thread in?

Some early 4l60e units had 5/16" line with larger fittings than the regular 5/16 steel line you buy from a parts store.

5/16" line steel is fine. no smaller!

check your fittings for the design / size they are.
