Trams bypass oil filter

[Term3]

"Trams"...... Stupid fat fingers I meant TRANS

Does the 5 speed transmission external filter only have flow when the transmission is up to operating temperature? I'm wanting to add a bypass oil filter and I'm wondering if I just need to "T" off the tubing going to the cooler or if it would be better to hook one up to the test port on the drivers side of the transmission which I "believe" is the pump discharge.

Subscribed also curious about this.

I would suspect the answer to your question is yes. The external filter is on the transmission cooling coil line. No reason to have flow in the coolant coil if trans is not up to temperature. Just my $0.02.

Yah I know for sure the 4 speeds are that way not positive on the 5 speeds, sounds logical to be the same. Would like to know where that test port is tapped into.

Bump up to the top.
Any transmission gooroos out there?

I've tried to flush a 5R110 before and it had to be up to op. temp before it flows into the cooler.

There is a Ford Tranny Tech floating around. He was a designer, I believe, of the torqshift 5r110.

This tranny has a thermostat in it. It opens around 165* if I remember right. When it is closed, there is still 10% of the fluid running to the cooler. (I'm saying this by memory, I'll try to find Mark Kovalsky's post on this.)

Edit: The TorqShift has an internal thermostat. It doesn't fully open until the trans reaches 170°F. If they don't use a heated machine the old fluid is just circulated in the trans and doesn't go out to the cooler line, so a flush won't work unless the trans is at least 170°F. (From Mark's post.)

And the torqshift 5r110 is a 6 speed.

No you are wrong, it is a 5 speed.

5 speed plus overdrive = 6 speeds

Here is a post from Mark K. I'm pretty sure he knows what he is talking about.

Torqueshift gearing:

hese are the numbers for an 05-07:

1st: 3.114 to 1
2nd: 2.218 to 1
3rd: 1.545 to 1
4th: 1.096 to 1
5th: 1 to 1
6th: 0.712 to 1
Rev: 2.88 to 1

These are for the 03-04:

1st: 3.09 to 1
2nd: 2.2 to 1
3rd: 1.583 to 1
4th: 1.096 to 1
5th: 1 to 1
6th: 0.712 to 1
Rev. 2.88 to 1



Also:


1st Gear applies the Forward, Low-Reverse, and Coast Clutches.
2nd Gear applies the Forward, Low-Reverse, and Overdrive Clutches.
3rd Gear applies the Forward, Intermediate, and Coast Clutches.
4th Gear applies the Forward, Intermediate, and Overdrive Clutches.
5th Gear applies the Forward, Direct, and Coast Clutches.
6th Gear applies the Forward, Direct, and Overdrive Clutches.

Essentially, the transmission basically operates as a 3-speed transmission with a gearsplitter, (the splitter being the overdrive pack).

1st gear is Low; 2nd gear is Low-"Over".
3rd gear is Intermediate; 4th gear is Intermediate-"Over".
5th gear is Direct; 6th gear is Direct-"Over".

Primary shift strategy shifts in the following order: 1-2-3-5-6. 4th Gear is skipped.

The only conditions under which 4th gear is actually used is under certain specified tow-haul downshifts; and primarily, cold-shift strategy.
