Noted 7AT Transmission Temps. (Street Driving)

[Tractionless]

I got sick of waiting for ECUTEK to add the .pid for transmission temperature logging etc., it's been years. I want to know temps. primarily to assist in the refill procedure, the same reason I installed a transmission dipstick.

I installed a Prosport oil temp. gauge sender in the OE hot line from transmission to cooler. It's positioned where the line enters the OE cooler; however, my OE cooler is no longer in service. Instead, I'm using a Hayden 676 core which is the exact unit Z1 repackages in their cooler kit. Btw, I only paid $30 for it on ebay. I'm running Valvoline Maxlife Trans. Fluid.

The core is mounted midship vertically between my Setrab oil cooler and the OE PS cooler and fed hot fluid from the top.

I put 7 hrs. drive time on the car this past weekend in 90*-93* temps. with heat indices around 105* and high humidity. Equal time was spend on both surface streets and freeway driving with wifey and luggage onboard cruising 80 mph on the freeway.

On the freeway the highest temp. I saw was 145* and "normal" was 140*-143*. Surface street temps. got as hot as 165* during stop-go and sitting at a red light. The temps. quickly drop below 145* once clean air begins blowing over the core again.

While I was unable to find a normal temp. range in the FSM the torque converter will only lock between 122* and 176* and I'm within that range.
