3 speed tranny going back in the car...
I just ordered a TH400 from Rossler ( www.rosslertrans.com) and should have it early next week...
I'm getting tired of not being able to keep a tranny in the car for more than a week, and have been wanting to try a 3-speed again anyways.
I should have the powerglide back in the next couple of days for some "farewell" passes with it. I was hoping to be able to have a 3 speed in the car in time for the GAFBA meeting at Silver Dollar this coming Sunday, but I guess I'll still be 'gliding along. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Hopefully the car will pick up a little bit with a three speed back in it.

Re: 3 speed tranny going back in the car...
How much quicker do you think a 3 speed with be? Could you get a quicker launch with a better converter in the glide?
How about running a taller axle ratio that will give you a similar ratio in first with the 3 speed as you did with the glide and use third like an overdrive and get a locking converter. It probably wouldnt be worth the trouble since its more of a strip only car.

Assuming he can hook up I can see and extra tenth maybe even two tenths with the th400 opposed to the glide. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: 3 speed tranny going back in the car...
Thanks for the link George! Those guys are driving distance for me. I think I know where to go for my rebuild now.
Out of curiosity, were there any special requirements for the tranny to work with our engines? (i.e. input shaft, output shaft, etc.)
Or did you just buy a standard TH350 from them? Wondering exactly what yoou ordered and what they are charging.
Thanks!

Re: 3 speed tranny going back in the car...
Reckless,
I have a TH400 in my car and I'm not using any yank parts at all. The tranny was built locally and is just a regular old TH400 tranny with beefy internals. In order to make the converter spacing correct I had to have a crank pilot extension made though.
George, You should head down here on the 18th of this month. It's TnT night at the track down here and a bunch of us from the local f-body club are going to be out there.

Re: 3 speed tranny going back in the car...
OK, lemme see if I can answer everybody's questions...
Nineball: Are you asking for a comparison between the 350 and glide? There really isn't a big difference on the street as far as driveability goes, believe it or not. There's just a noticeable amount of extra slippage from takeoff (since there is a lot less overall gear ratio than a 3 speed). OTOH, it's pretty cool to downshift into low gear @ 50mph and so and smoke the tires <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> At the track, I don't really have any direct comparisons, since I never got my 350 to hook, and I'm also running a totally different torque converter now. Also, FWIW, I had some issues with tuning (that I didn't realize at the time) the whole time the TH350 was in the car previously. I expect the TH400 to have the same characteristics of the 350, but it is a little heavier and should be nearly indestructable in my combo.
dug: Way too much trouble/money. Plus, the GV overdrive is pretty heavy, so all of the advantage of the powerglide would be gone.
BHB & Chris: I think I should see at least a tenth or so. Hooking the car shouldn't be much of a problem. Remember, I have a different converter now than the last time I had a 3 speed in the car. The 8" converter I have now is a "soft hit" converter, and doesn't hit the tires nearly as violently as the previous converter did. I'm also going to be trying a stiff sidewall 28x10.5 ET Drag on the car (just released by M/T). I think my current 4.33 gear and 28" tire are about right.
Todd: It's been well over two years since I initially did away with the 4L60E. Nothing special is needed. The basics are the tranny itself, modified crossmember, shifter, converter, and driveshaft. The TH350/400/glide bolts right to the LS1 and uses a total of 5 bellhousing bolts.
Will: I may have to do that, since I may not be able to get any track time with the TH400 before then. I want to do as much tweaking/tuning that I can before the Thunder Shootout.
rnr27band1: Hopefully I'll have the glide back by this weekend so I can make it to the GAFBA gathering. I look forward to meeting some of the local guys.

Re: 3 speed tranny going back in the car...
Thanks for the replies, but allow me to be more specific if I may.
I have a Yank TH350 and a Yank PT4000 converter. Can I just reuse this converter on a standard TH350, or will I have to use the input shaft from the Yank tranny I already have?
Todd (dumb *** tranny guy)

Re: 3 speed tranny going back in the car...
Todd, I'm not sure about that one... If it's a standard TH350, then you could reuse the converter on whatever you wanted. If it's one of the custom jobs Yank does that retains lockup and lets you use an "LS1" converter, then no, you couldn't use it on a regular turbo tranny.

Re: 3 speed tranny going back in the car...
MacGyver:
Is the crank pilot extension a slip on piece, or do you actually weld it to the converter??
Thanks.

Re: 3 speed tranny going back in the car...
The pilot extension just slips on over the hub on the converter... There are different thicknesses available, as guys that use mid-plates have to run one to keep things spaced properly.
I have one that I don't use because it's just a hair too thick (right at 1/2").
Most any converter manufacturer should have them in various thicknesses.

Re: 3 speed tranny going back in the car...
Why not keep the th350 and use the stronger th400 parts? I did and am very happy with it...There's a weight difference also!!!!! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: 3 speed tranny going back in the car...
I think gear/tire combo is going to be critical for George to hook that TH400.
Maybe a 29 inch slick and 4.30s with 5000 stall? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Cheers,
Chris

Re: 3 speed tranny going back in the car...
rnr, I love being in control of my car. Thats why I hate electronically shifted automatics. A TH350 with a manual valve body and a transbrake does almost everything my M6 does:
1. Violent launches!
2. I can shift where I want, when I want
The only drawback is it doesn't have the 0.50 overdrive for the freeway <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
I'll only do the swap if the T56 blows up anyways, not sure when that will happen. I have a fresh rebuilt spare T56 on standby anyways <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: 3 speed tranny going back in the car...
This was the way I was told from Gilbert @ Transking ( THE BUILDER )that to freshen up the th350 with 400 parts (drom,upgraded billet shaft,clutches etc.)and It would be stronger and reliable as the 400 but ended up costing me $2000 but he told me that he would back this tranny against any 400 and save the weight so I was <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
