I wouldn't pay the list price of $3100 for one. At that price I would buy a much stronger 4L80E from e.g. Jake. The GM one won't have the billet input shaft and other improvements you should have when going over 700HP.
I'm no expert on the 4L8xE, but you are asking for opinions.

I could build a substantially stronger 4L80E with billet parts including core and basically all of shipping for that price, if that gives you any perspective.

Billet Input shaft, mainshaft and fwd hub included? plus torque converter..

NorthTexasConverter

Everything listed but the billet main shaft. That would be a bit extra. However, it's unlikely you would need the billet main shaft and not some kind of alternative for the intermediate sprag setup as well. You honestly may not be at a point where you need either of those in fact. How much power are we talking about here, what kind of RPMs will the car see and what's the weight?

Converter would also be extra. It looks like they have just a plain old stock converter pictured, so if a converter DID come with that purchase, it would be pretty far from being considered "high quality" from myself and many of the other builders on here.

Jake's Performance

I never have understood the draw to Rossler's stuff. There are a handful of proven builders who build as good or better product AND give tech help online.

I can understand his philosophy for internet business but after having one of his TH400's apart a few weeks ago... Not impressed.

And Rossler doesn't give out any free advice here or help non-customers on this forum as do Jake and some of the other sponsors.
If you are getting benefit from this forum, then support the sponsors! Especially those who's product is at least as good as and similarly priced to those from non-sponsors.
I know that all the sponsors here work very hard and put in a lot of hours and have very competitive prices.

THIS

I assume part of it's because so many people who participate in Hot Rod Drag Week and other events all seem to have Rossler TH400s with a Gear Vendors and word spreads that way I suppose.

Having had one of his 4L80Es opened in the last 6 months did not exactly blow my mind either to say the least.

The way I look at it is pretty straightfoward, maybe a Rossler fan can chime in with their rebuttal but here's how I see it.

4L80E manual control box? $300 from Rossler, $150 or $200 from either us or Jake.

Transbrake? $600 through Rossler plus the cost of a required deep pan. A similar functioning, yet faster engagement and release from either Jake or I (neither of which require a deep pan)? $500-$600 and that's it.

Here's Rossler's high end TH400 offering list.

Basically what you're looking at is either a Level IV TH400 from us or a Level V from Jake. You pay $3,800 through Rossler for that, while you would pay ~$3,350 for the same exact thing from me, but my price also includes the core and comes with a one year warranty.

Sorry to seem like I went on such a long rant, but I just figured now was as good a time as any to clarify on what you're getting vs what you're paying for

True this. Had to call his shop 4 times in August to get a copy of the instructions for his transbrake for a customer transmission that came in here with it. Too many issues, had the same issues in the past with a previous customer trans late last year, so we ended up swapping it out for our brake and VOILA, not only did it work flawlessly behind the 1,250rwhp combination, it performed much better than it did before. Customer was very pleased as far as I could tell.
