Default Transmission time!

So, as I've discussed with people, the direction I'm taking with my 1995 SSEi is pure power. In not that long, she'* no longer going to be my daily driver, but my science experiment, plus go fast car.

In speaking with a number of people who are extremely familiar with the Series 1 L67, I've come to the conclusion that my goals are possible. I'm not going into this blind; I know I'm going to have to make a significant investment in time and money and that if I want this little "experiment" to succeed, I'm going to have to learn an awful lot about my car.

Lectures on how its not possible, or go get a Series 2 are really not needed, thanks. I appreciate the concern many of you have shown for me. If I screw up, I screw up.

Anywho, on to the topic:

I've been speaking with the transmission mechanic (a close family friend), and I've shown him the information found in Willwren'* transmission rebuild threads. Basically, what I'm planning for the transmission is from the lessons Mr. Wren learned.

http://www.bonnevilleclub.com/forum/...ic.php?t=40296
http://www.bonnevilleclub.com/forum/...ic.php?t=41290
http://www.bonnevilleclub.com/forum/...ic.php?t=30609

I am having him put in the SK 4T60E-Jr kit, with all optional components. I'm also having him bypass the radiator and put on a nice fat external cooler, plus a seperate trans temp gauge for the cockpit.

Why am I doing this when my transmission isn't bad? 160k miles on this transmission (still the original). I think its due for this, and I might as well get it done at the same time as having a shift kit put in.

Now for the questions:

Should I have the valves replaced?

What about the torque converter? Bill, did you replace the torque converter because yours went, or because that was one of the things you did to support all your mods and put more power to the ground?

What else should I do while he has the car there?

As of now, based on many people'* advice, I'm not having a limited slip differential put in.

Thanks in advance for your advice folks!

Valves? Do you mean valve body or the solenoids?
It'* a good idea to replace the electronics while everything is apart.
As for the converter, IMO you should upgrade like bill did.
If your going to drive you car alot and care about mileage then keep the same stall. But if your going to take it to the track alot, you may want to get a stall that it slightly higher than stock. But then agian since the S1 L67 powerband is in the lower rpms, you should be fine with the stock stall.
Replace the rear main seal while the tranny is out. It'* just one of those 'while I'm in there' kind of things.
You may just want to wait untill your trans goes to rebuilt it and have the money put aside for now.
And remember while modding your car, you can only pick 2.... (fast, cheap, reliable)
I can't tell you how many times I've had trouble with my car because I wanted to make it faster.

Fast and Reliable, thanks

Why should I wait for the transmission to go when I'm ready to make this move now? My other concern is taking a 160k transmission on a 6500 mile round trip which I'll be doing in July

I'm not worried about mileage as this is about to become my weekend / warm weather car.

I'm going to leave the stall alone, for the reasons you stated

Change all the electronics, and change the rear main seal, got it. Go for the heavy duty TC. Got it.

Yeah I do see what your saying about the trip in july.
One reasonI was suggesting that you hold off till it breaks is so you might have more money for 'just in case' situations. I put a butt load of $ into my heads this past summer then 3 wheel bearings went. Thats $450 right there. I dunno about you but scraping together $450 after spending over a G in parts was pretty hard.
And another reason to hold off is to see how Bill and SSEimatt93'* trannys hold up. I'm not trying to say they got thier trannys built bad/wrong by any means. But what If issues do arise? You'll have the piece of mind that it worked out for them.
Not too many people have thier 4t60e'* built.
You could also look into how other people build thier trannys. www.60degreev6.com has some people putting good power through 60e'*, and fireo guys do as well.
You can never research too much or too long.
Besides, it'* going to be cold out for a while still.

That'* just my $.05.

I can tell you that I've put my trans through it'* paces on a daily basis for some time now. Not a single hiccup, nor do I expect one. 4T60'* have learned all their lessons.

Get an adjustable shift modulator as well.

Financially things are looking up for me this year. Not that I plan on throwing money out the door for no reason, but I intend on learning and doing. I want to have fun with what has become a really great hobby. I will look into that website and believe me, I'm going to take everything I see to heart.

With regards to Matt and Bill'* rebuilds, I have alot of faith in that kit. I know that Bill kicked the things butt and I believe that the kit'* going to do wonders for my transmission as well.

Alright, going to make sure that is replaced as well.

So far, I have:

The SK 4T60E-JR Kit with all options
Bypass radiator and large external radiator + temp guage
Change out all the electronics
Change the rear seal
Heavy duty torque converter
adjustable shift modulator.

You are going to want everything in your differential to be repalces, side gears, thrust washers, case pin, lock screw, all the goodies, basically a new nest kit. This is if you dont go with a limited slip unit an is LSD, pricey. I asked the same question a while back, then spoke with some gearheads at work as well on the forums. Decided not to.
I can tell you the shift kit is amazing.

Can we use your car as a test for one wheel wonders on the 28th and burn off the old tires you will be getting rid of?

Okay so... you're saying have the following done to the differential:

Side gears,
thrust washers,
case pin,
lock screw,
Define all the goodies?.. or a better way to describe this when I tell Dave exactly what I want. I'm not doing the LSD Matt.


The list so far:

SK 4T60E-JR Kit with all options
Bypass radiator and large external radiator + temp guage
Change out all the electronics
Change the rear seal
Heavy duty torque converter
Adjustable shift modulator


Keep the ideas comin
"Stuff" to the differential
