You were quoted a 4L80e and not their A41 kit which is a 4L60e, right?

4l80e
I made the final decision to run a 4L80E behind the 496 in my 73 Coupe.
The estimated torque/hp for my motor will be between 600-650 so a level III will be necessary.
Now my question is where to purchase it?
I received a quote from Silver Sport Transmissions for their complete kit at roughly $5,600.00 which is stated to include all new parts and hardware and the parts list appears to include everything.
When I priced the parts individually the total cost isn't much lower than their kit.
This is over my budget but I'll pay the price if the kit is complete and their parts are top quality.
Has anyone purchased through Silver Sport and are you happy with their complete kits and customer service?
Is there another top quality builder who you recommend that can deliver a top quality kit or components I can receive a quote through?
Thanks, Greg

Thank You.
I guess my search on where to purchase a 4L80E will continue.

I've seen complete kits for about $5000. I wish I could recall where.
Still, I've seen built 4L80e's that would be suitable for under $3k at a few different online shops. Decent converter is maybe $750. A controller, wiring harness and TPS setup is something like $800. Then, you need to figure out the transmission mount and the driveshaft.
From what I've read, a stock component 4L80e is mostly OK except for the direct clutches. It should reliably stand-up to your engine with some hydraulic work and performance direct clutches.

Be interesting to know what level of converter is included. I had a Yank 3200 behind my LS 427" LS2 stroker that was rwhp at 500 hp.
It was great. Drove like a stock converter until you nailed it.
I assume the controller is included at that price.
Tons of advice on LS1 Tech forums in regards to 4L80E applications.

Think TH350 vs. TH400. Same concept with 4L65E vs. 4L80E.
The 4L80E is a bigger transmission which provides more power capacity. Both are 4 speed automatics.
The A41 Stage III has upgraded internal components and easily handles 650 torque input. We also now offer a close ratio option which provides a 2.84/1.55 1st/2nd vs. the stock 3.06/1.63.
Link below provides more insight into our A41 program. Yes, I realize it's written by a Mopar guy but you'll just have to suffer through it.

SST's kits are truly complete and I highly recommend them. They were great to deal with when I purchased my TKO600. They patiently answered every question and even half way through shipping I decided at the last minute to go with an internally balanced setup. They swapped out my flywheel even though it had already been shipped and was half way across the country. They didn't even tell me there was a shipping issue, it just showed up correct. Very impressive.
As far as a 4L80E, not sure it will fit in the tunnel. I looked at that myself. The 4L60E looks to fit but is VERY VERY tight. Many will tell you it won't fit either. The 4L80E will likely require nearly a complete tunnel replacement I would think. The case is massive and really meant for a truck application.

No case dimensions here, but good info regardless.

It easiest to see a picture. Overall, from the back end of the TH400 pan forward they are quite similar. You can read a few comments in further posts about the 4L80e fitting in a few different cars fairly easily too.

The fact that the TH400 did come in C3's is likely why the 4L80e fits better than most people predict it will.

I just spent about an hour on the phone calling several transmission experts who do O.D. upgrades and sell kits. They all said the same thing, and that was they could make a 4L80E fit into a C3 but would not guarantee there would be no tunnel cutting or modifications. They recommend modified 2004R, 700R4 or the 4L65E to take the hp/tq of my engine build. We also talked torque converters, lock up and stall speeds. In the end they all asked me the same question. Why not put in a TKO 600 and be done with it? I may just follow their advice and make it simple.
Thanks for the comments and advise from all.

There have been people who have done the 80e swap so it’s proven to fit. I have one in the shop now I’m gathering up parts for to swap into my 74. Basic mods and a shift kit and the 80e will hold 750 hp

I have the 4L80e in my car with a SBC 427 MPSFI .
DO NOT BUY these on line kits ..
Every town/City has a good trans shop.
Buy a core , make sure the cooling lines are located one front one back NOT the case with both cooling lines up front like a TH 350. The reason is the spread port cooling line provides lubrication to teh rear areas making it more stout .
NO TUNNEL MODS
STOCK SHIFTIER WORKS
I bought from E/Bay . 4l80e Banjo fittings for the cooling lines gave me good access to the cooling line connection
TCI Controller (499.00)
PTC 3600 Stall 10.5" Lock up Converter ( 750.00)
Made my own cross member from Chrome molly tubing
Drive shaft HD Joints local Drive shaft shot 1350 joints 150.00
th400 Yoke 50.00
Core and complete build was 1500.00 ( Local Shop ) Unit is 2 years old and stout as hell
Oil Cooler Trans fluid I was under $3500.00

Jake in Dallas is probably the foremost authority on 4L80E's, at least in my world. He was the first to market a transbrake for it.
He has commented that the revision where one cooling line has been moved to the back of the tranny has no effect on transmission temps, which is what it was supposed to help with. I'll use one of the older ones with both lines in the front on her '78 behind an '03 LS6.
A stock 4L80E will handle anything a N/A smallblock or LS can throw at it.
Mine will have a TKO600
