Preparing to remove the auto trans in my 2012 V wagon in order to install a billet, triple disc converter, and was wondering if anyone has done this with long tube headers installed, mine are Kooks. I'm planning on removing the headers, but I thought I'd ask if anybody has r&r'd the trans with the headers in place? It certainly looks like it will be MUCH easier if I remove the headers. (I've removed the exhaust and driveshaft already, this pic is the only one I had at my fingertips)... thanks!

Do you drive that? Looks pristine.
Sort of like those videos that I see from the guys using dry Ice to spray clean.

Oh, and yes you'll need to remove the headers - at the minimum loosen them up and zip tie them out of the way as much as possible . The bell housing will hit them as you try to shoe horn it out.

I have a manual- but with the auto you'll probably have to lower the subframe some to clear the top of the tunnel and get the proper approach angle for the transmission to line up. It is a tight fit.

I do, but not often enough probably and then only a few months out of the year (it's not a "daily") Thanks! I was fortunate to find a one-owner low mile car in 2018 after an exhausting 2 year search. I try and keep it looking as good as I can, I love this thing!

Kind-of Off topic but I thought the stock converter was more than enough for a blower car.
Well I can only tell you my experience the past two years, and I was unable to get the stock converter to stall more than 1,100 rpm. I made about 12 passes this summer and the 60' et was between1.59-1.63 on every one. The new converter is built to stall at 2,600-2,800, if I can keep the DR's hooked, hoping for an improvement in ET.

Thanks Mark.

The trans is bone stock. I ordered the converter from Precision Industries.

Precision Industries makes a nice product. We dealt with Terry for several years he definitely was a pioneer in the transmission industry and I'm sure his family will continue to make quality products. I don't know how long you've had that converter but Terry passed away about a month ago. Terry always had time for his customers and peers. Is that a 265 or 258?

Good to hear. I've had it for about a month, Precision was recommended by my tuner. I chatted with Jack from there, didn't know Terry however the website indicates he passed away in Nov. 2020. I don't recognize either of those numbers, it is the billet, multi disc lock up for the 6L90 trans though.

Is that seriously your underside?? That shit looks like it just rolled off the assembly line! Maybe even better!!
Haha, yes that is the underside. Not to highjack my own thread, but here are a few detail shots... I'm very fortunate to have this car.

That being said, I will remove the headers completely, the fitment was a dream, I'm pretty sure they will come out just as nice as they went in and I've got all winter to do it ;):)

Thanks for the kind and helpful comments, this forum has been terrific, and I'm having a blast learning all about these cars!

The number is the physical size of the torque converter. Your stock converter is a 265mm and 258mm for a quick reference would be in a I6 Trailblazer. Knowing Precision its probably a 265mm which will be fine. Are you running a stock cam?

Appears to measure 265mm. Yes stock long block incl. cam. Discussed the current combo with Jack @ Precision before they built it. Hopefully it works as he suggested it would. Looking forward to May!

You need a better cam. Stock cam is garbage.
Haha, can't disagree with you, however that stock cam propelled the wagon to 124.37 mph in the 1/4 last year spinning an easy 6,000 rpm at corrected altitude of 3,100', so there is that. ;)

Thanks! 14 days of "self isolation" in the spring of 2020 "may" have had something to do with how it looks today LOL :)

UPDATE: for those that are interested; R&R'd the trans this weekend, and it really wasn't difficult at all. Would recommend another pair of hands just to help steady the trans on the jack when separating from the engine, but otherwise it's straightforward (and NO, you DO NOT need to lower the subframe ;) ).

I just can't believe how clean the undercarriage is. Mine looks like a crack whore they pulled out of a ditch by comparison.
