I’m glad we had this discussion. I will add to it. I was doing research as well and decided to email the guys at PSC. I explained my setup. And they said any of their fluids will work as well as the ac delco power steering fluid. All because it has strong anti foaming agents. It won’t hurt any of the seals or swell them in either the box or the the pump

Edit: @NeverFinis was accurate with his PS fluid part #s

You guys are scaring me. Never knew you can use atf as power-steering fluid. "I've used Prestone in GM vehicles for a very long time (including my 20 year old truck) without any problems." Gm powersteering fluid. I'm using prestone and pump shown, hope it's okay. Guys on the ls swap said they haven't run into any issues using prestone.
By the way off topic. I'm installed the PSC flow control fitting after reading the link below. Really like the responsive feel of the steering. Before it felt like steering my boat when driving on the highway.

That's interesting. I've been running 1400 PSI Saginaw pumps on 80 series for over a decade. Never had a leak or negative mannerism.

I feel the Saginaw pump is a big upgrade over the Toyota pump. Decreases steering effort at idle and doesn't restrict steering movement as much in an emergency maneuver situation if you let off the gas and slam on the brakes.

I was gonna say, Im running this pump and ill deal with the consequences later. I didnt try to budget build my swap but my wallet is hurting right now hahaha....almost done....air intake, fluids, and wiring.
 
Hope you guys are doing well. Have a question regarding the transmission cooling system. I’m not using the LC trans oil cooler but the derale. Even with the derale cooling fan on. My trans tempt reached 210-220, seems high. Operating ideal tempt should be around 175 to 200. I added another 8 pass trans cooler (left), right derale. Haven’t drive it on the road so no clue if the additional cooling condenser will help. Bottom of the stock Toyota radiator, there is an inlet and outlet. What oil goes here, oil or transmission oil?

I used the factory Toyota radiator and transmission cooler. On the high end so far my temps get to maybe 145* but it's also fall time here in Oregon so it's getting plenty of external cool air.

Transmission ->Right Side of Radiator ->Left Side of Radiator -> Bottom of Cooler -> Top of Cooler -> Transmission

I am using a Ron Davis radiator, because I already had it, and the stock Toyota Transmission cooler. I have not noticed abnormal transmission temps with my 6l90e.

This is my exact setup with electric fans. I shouldn’t run into any issues once I get it driving. I do not have a trans temp gauge and probably won’t be installing one any time soon either lol.

Something definitely isn’t right. Mine has never ever reached that temp. Even towing a 20ft boat on the highway. My cooler is not huge either. Mechanical fan.

I have an AWD Chevy Express (same drivetrain) and it hit those temps pulling long hills in August running 80mph fully loaded on the highway when it had NO AUX COOLER AT ALL. Only looped through the factory radiator.

What transmission?
4l60 IIRC
 
Sorry forgot to mention.. it's a 4l60e. I should have gone with the more robust 4l80e, but bought the mark's adapter long ago. These trans known to fail so I need to make sure that are running at low tempt. i installed the trans tempt sensor to the pressure port. Was reading on a ls group last night, some guys mentioned installing the trans sensor there will give false reading, higher. I will use a thermo gun to read the tempt after a drive later. I will drill the trans pan at next fluid change.

"Transmission ->Right Side of Radiator ->Left Side of Radiator -> Bottom of Cooler -> Top of Cooler -> Transmission" I will try to run to the radiator if it still runs hot. However, wonder if running the trans fluid through the radiator is a good idea... what if there is a crack inside the radiator and trans and coolant get mixed up.

Yep, your sensor location is the reason it’s reading so high.

There are several ways you can read the actual trans temps the ECM sees. The cheapest being an UltraGauge.

 
Thanks all for the inputs.. off topic. If you going to change your exhaust gaskets, don't get the cheap chinese ones on amazon but get the remflex brand. They more more expensive but are thicker which helps fill in the uneven surfaces.
I had exhaust leaks and engine was running lean/rich. I reweld the leak areas. No more leaks/code and engine runs better. Used the cheap gaskets resulted leaks, going to install the remflex ones. Reddit on remflex.

Swap is much easier using a premade harness from a quality supplier. They should use OEM quality connectors, and automotive grade wiring.

I went with the OEM harness that came with my motor. It was much more work, but cheaper, and should be more reliable compared to aftermarket. One does need to make a relay/fuse box, which is a huge downside compared to pre-made harness.

I thought about doing the wiring myself from a factory harness but those reasons alone are why I spent the money on Speartech. It’s costly but damn it’s quality.
