Transmission thermostat

Does any one drive with the transmission thermostat pined to keep cooler temps

 

"Wha-cha doin' Vern?"

"I'm fixin this here transmission thermo-stat thing."​

"But why? It ain't even broke."

"Well I'm gonna fix it til it is."​

 

Lol I guess there a dumb ass in every form

 

I kept the trans thermo pinned on my 07 Tundra for 100k and now my 19 Tundra. No side effects, same mpg pinned or not, and definitely ran cooler. But it is a different trans from the tacos.

 

Yes it’s fine

 

It's not good in winter, the trans wants heat and it warms everything up faster.

I would only pin on long trips with load. Even then I trust it to work.

 

I pin mine while towing. Makes a significant difference with keeping temps lower.

 

Awesome that’s what I wanted to hear thanks

 

What do you use to pin? I think I’m pin mine for this weekends road trip. Going to be 100 degrees. Driving ten hours in a Tacoma.

 

Use a cotter pin

 

wait first time i heard this , how do you do this ,anyone have pics?

 

Whaaat?? Somebody going to have to 'splain this 'pinned transmission' business to us MT guys.

 

Someone Talk to Me About Pinning the Transmission T-Stat | Tacoma World
Basically forces your transmission fluid to run through the factory trans cooler instead of waiting until it hits 195F for the thermostat to open. Good to do during hot weather months, folks recommend unpinning during winter. Think toyota stopped adding trans coolers after 2020

I read that MT's run cooler and you don't need to worry about it
