I got a quote from my tranni guy I've known for years. I want to swap out my TH400 for a 4L80E.

He quoted me $4000CAD TAX IN ($2500USD) for the complete swap. It includes:

- 4L80E tranni
(Built will all the best parts, red Reybestos clutch pads, shift kit, deep pan, bullet proof guarateed to easily handle 600HP+, all tricked out and special modifications he develeloped and passed on to General Motors a few years ago to make the tranni better)
- New Stall Converter 3000/3500
- Full computer module with adjustable knobs for shift points etc.
- new Chromolly drive shaft and large yoke
- kickdown switch for carb linkage
-oil dip stick
-completely installed out the door.

He also gave me 1 year warranty on this performace tranni.

What are your thoughts first off, maybe your past experiences with this tranni and what you think about the price?

Thanks in advance.

Sounds reasonable if you install an extra trans oil cooler.

How much does he do one for a truck, meaning, a bolted yoke rather than a slip joint? This is ready to ship out the door.

You could go to Jet Performance site and check, they do the same thing, but, no install.

I live just 15minutes north of Toronto, Canada, if you want I can email you his phone # and call him directly.

Thanks.

Anyone know the weight difference between the Th400 and the 4L80E?

Thanks.

That sounds very low to me. I've never seen a stock 4L80E with the computer and converter for that price, much less built and installed. I'd jump on it if that's the way you want to go.

I give him a lot of business, so he helps me on the price. PLUS I found that performance work is cheaper here than in the USA.

Any other opinions?

That's one hell of a deal. I work for a major performance shop, and even with my discounted pricing I can't get a built 4L80e and converter for that, not to mention the driveshaft/computer/install.

JUMP on it.

Yes, I've been getting that response from everyone. I've been dealing with this guy for a while now. I like his work because he is very miticulous (sp?) and does not cut corners to save money. He stand behind his work, plus a 1 year warranty, unheard of in performance places around here!

I was thinking, since it is a good deal to upgrade to the BLUE REYBETOS clutches and make it even more bullet proof. I believe he said another $300CAD about $190USD.

What are your thoughts about the tranni, I heard that it had been reported to drop tourque #s by as high as 25% because of the weight! Is this true?!

It is a pretty heavy transmission. What kind of motor are you running? I'm not saying that it is a bad deal on the trans, but maybe it is more than you need? If you aren't running a real powerhouse of a motor, maybe you could get by with a TH200-4R and save some dough and not go through the installation difficulties of the computer tech and the size of that trans? If I recall, it is a tall transmission and might require some floor massaging.

It should be just like a 4" to 5" longer TH400! pdq67

I am running a 350HP 454ci, I also plan to rebuild the engine to push 500HP straight motor + 150 shot NOS next spring. So I want to be prepared. What I like about this tranni...

1. O.D
2. adjustable shift point
3. converter lock

A 700 or 200 R4 tranny could be built to take what your talking about. For a lot less money. The 4L80 is awesome, but I wouldn't bother unless your making 700+ hp.

The more and more I think about this I am kinda undecided on this tranni. I am told from many people not to go with this tranni BUT with a built 700R4 or 200 instead.

Now I'm confused! HELP!
