Those with Stalled Autos

[Jtaugner]

Quick question, just got my PTC Torque Converter, all my Chevy friends are saying I need an additional Transmission Cooler, is this common with the new 5.0's and the 6R80's?

Are ya'll seeing higher trans temp #'s with a stall? I've been looking at people's signature's and it doesn't seem to be a common mod.

These cars come with factory trans coolers.

Even with my Circle D 2B 258mm converter, casual driving, trans fluid temps never rise higher than 185* to 187*F.

I figured the stock was good enough, plus judging by how few people actually had an aftermarket Trans Cooler I figured the stocker kept it cool enough.

When you did your TC, did you put better fluid in, or stick with the stock fluid? Any noticeable difference from say RP vs Stock?

 

[UnleashedBeast]

I sure did, you will not catch me sticking with stock fluid.

Amsoil ATF LV - requires 12 quarts for a full fill, however, I could only get 10 quarts back into the system for a full fill. That means 2 quarts was retained in the external cooler and valve body of the transmission. I tried to pump fresh fluid into the cooling system, but fluid kept spitting out all over me. I gave up, since the car only has 3,100 miles on it.

Was that after the 1 that you're supposed to put into the TC itself?

Exactly what I see with the 4C.

 

[Jtaugner]

Did any of you install it yourself?

I have access to a lift and all tools, how long would I expect to be at this? I've got two extremely mechanically inclined people plus myself.

i did mine in the garage on jack stands , took me about 8hrs.

Yes, that included the prefill of the TC, and I did the install myself with the help of a friend on his lift and transmission jack. I wouldn't want to do it on jack stands. Yikes!

Then we know the thermostat and external cooler are working as intended.

Do you have to take to the Dealer after for anything? I remember reading some people needed too for something just can't recall.

I know you need to get an updated tune....

Anyone have a 4c with 4:10's?

 

[UnleashedBeast]

I didn't have to take mine in for anything. It cranked right up for the test drive.

 

[Jtaugner]

Just picked up my case of ATF from the dealership yesterday, ready to get this thing in.

Is there a guide or how-to on dropping the tranny?

 

[Deespeed99]

Look up online for a 2011+ service manual. It was pretty spot on for me when it came to it.

Yes I have 4.10's with a 4c...works great with a boss intake, with a stock intake i'd go 3.73

No cooler change required. Been running mine since 2012 with no issues.
