This new tranny is rated at 650 horsepower. Will it be a direct bolt on into an ls1?

strife

they are already mated to ls1 in some holden applications

So the wiring and stuff is compatable.

Hello,

The 4L65E is already in the 04 Silverado SS. You can check your glovebox option list for RPO code "M32". If it is there (it should be), you have the 4L65E trans.

Here is the specs right from GM's website:

Enjoy!!!!!!!

BTW-

It is rated 670 lb-ft "gearbox torque" and 380 lb-ft "engine torque".

Leave it to GM to cunfuse us once again.

Hey, there is also a 4L85E out now that is sometimes used behind the 8.1L in 3/4T trucks (if they didn't get the Allison).

It will bolt up but wiring may be fun

It is RPO code "MN8". Here are the specs--

A bit off topic but: What is the strongest 4 speed with O/D you can put in these things anyway???

Linear Velocity

iTrader: (1)

A 200 4-R.

Debian Dog

Thought those were a 3 speed with overdrive....

Linear Velocity

iTrader: (1)

they have four speeds.

1st 2.62
2nd 1.43 (I think)
3rd 1.00
4th. .69 - overdrive

i've got a 4L65E in my Z. its almost a direct bolt-in for the 4L60. the only things you have to swap off the old tranny are the tailhousing (6 bolts) and the shift lever (must drop pan, takes about 15 min to swap)

Can a 200 4-R be beefed up better than a 4L60E? If so, can those internals be installed into a 4L60E housing?

Debian Dog

It can be installed See sponsor site but not in the same housing (or rereading maybe it is real close). I would like to know someone that has one and how they like it.

Here is the specs on the 5L40E. Nothing offical yet on the 50, B T, but in your link it mentioned 311 lb-ft, which I think is pretty weak.

http://www.gm.com/automotive/gmpower.../apps/5l40.htm

If you'll notice on the right side in the applications they show several BMW's that use the 5L40E. I guess that says something for our "lowly American cars"

Hughes claims that their street/strip 4L80E will live with up to 1000hp and I've heard that FLP says they can build a streetable 4L80E that can take up to 1200hp.I don't think a 200R4 can be built that strong.The gear ratios for a 4L80E are 2.48 1.48 1.0 .75 so you get closer spacing to.

quick curt

The 4L60E can be built to withstand high horse applications.It uses vacuum modulation for low speed shifts and computer controled line pressure shifts at full throttle.This thing bangs like a turbo 400 with a shift kit. I got one and luv it.

Yes, i have mine built pretty-dang-good (Blue Plate Clutches, Reaction Plates, billet servos, Raybestos Bands, etc) but if/when it breaks I wanted to know where to go. The FLP level 5 looks sweet and the price looks "reasonable"
