Hey guys, I had a change of heart, me and my dad were talking and decided to instead of throw the new clutch in, to go ahead and swap for a TH 400. What do you guys think?
Id like the durability of a TH 400 but I'd also like OD... should i go with a beefed up 4l60e, i know alot hate them, but I do daily drive this car some and dont want to spend the extra 2 grand on OD for the 400. Or should I just go with the 400 and sacrifice some highway driving?

Also I know some have the 400 in their car so can someone tell me everything ill need and my final cost when all is said and done. Id really appreciate it!

Also If anyone is in the market for a Spec Stage 3 clutch, let me know, mine is for sale, brand spankin new in the plastic!

 

Your gona need
A Diff Driveshaft and Yoke 400$
A new trany cross member 400$

Unless your making some serious power i whould just get ur 4l60e Rebuilt.
Take a look at this link for parts
www.spohn.net

 

I dont actually have a 4l60e, I have a t56 right now and want to convert to an auto...

 

why whould u wana do that. t56 makes it so much more fun to drive. I whould leave it unless its an all out 1/4 mile car

 

You need to post this in the "Drivetrain" forum. I can help you out if you post it where it belongs

e.g. you can install the TH400 with a little work to your T56 cross-member.... it doesn't cost $400.

 

just paid 400 for one for my 3rd gen with an adjustable tk arm

 

A major factor in determining how tolerable the car will be w/o OD is the rear gear you are running. I am running a 3.42 and it is borderline. Eventually, I will spring for a GV OD. If it were a shorter gear I would say it would NOT be tolerable in any kind of highway driving.

3rd Gen does not equal 4th Gen

Most people that need a TH400 have already moved their TA mount to the chassis.... e.g. Spohn, BMR, Madman, etc.

TH400/Gear Vendor and T56 modified cross-member

I'm with Rich... with 4.10's on street tires, I was pulling almost 4,000rpm at 70MPH cruise. The Gear Vendor dropped that closer to 3,000RPM.... better, but still not "street" friendly.

There is a thread on the "Advanced Tech" forum detailing, with pictures the install of a 4L80E.... O/D, fully electronic, and able to handle loads of torque.

 

i posted this in the drivetrain forum too for ya fred, dont know if i could have moved this whole post...

 

I can't move anything on LT1 Tech... its not "my" forum.... Brent, Chris, etc. have this forum.

 

I'll move it for ya

 

hey fred, can you give me a clue as to what all i will need so i can price this up, id really appreciate it!

 

also where is the best place to get a TH 400 from, TCI?

 

Tranny (preferred source is Rossler Transmissions at www.rosslertrans.com)
Tranny pan
Inspection cover (if desired)
Converter
Flexplate
Modified K-member
Chassis-mount torque arm
Shifter
Dipstick
VSS reluctor and sensor
Tranny Cooler
2-pedal assy (if desired)
Driveshaft
Tranny shield or blanket (if desired)
Computer reprogramming (to get speedo to work properly)
Tranny fluid

I probably left something out.
