Well, I bit the bullet...

[DavidT]

the sho is in the shop for a tranny rebuild. The P1744 code combined with constant tranny puke was too much for me to ignore. However, it seemed to perform just fine. I was quoted $1700. They are going to put in a transgo shift kit, and I requested a fully brazed tc (these would be in addition to the cost).
How will the Xcal tune work with the shift kit? Any particular spring need to be installled for the 1-2 shift?
Thanks.

You already have a tuner? The Xcal tune is a custom one (or should be) and will work any way it's programmed.

Although there are hardware tricks that the programming cannot accommodate. I've found the HD tranny that I had rebuilt will push pressure way past what OEM is.

 

[DavidT]

yes, I have Doug's tune, and I love the way it shifts with it. So, I am assuming to keep the shift kit install as near factory as possible, and let the tune do the work, no?
All I am looking for is a long lasting tranny (I am at 127,000 miles now). I do not care about racing, track ET, etc... Maybe occasionally getting a heavy right foot
BTW, thanks for the reply (I see the forum is keeping tabs

my tranny rebuild included a trans-go kit with the regular springs (vs. installing "yellow(?)" springs for tighter shifts).
the results are that my SHO shifts like stock w/out the XCal program.

then i added the XCal program to give me the firm shifts.

i can always choose to return it to stock.

some on this site have said that if you install the optional springs, a programmer isn't necessary. however, w/out the XCal, the air/fuel remains stock.

so, i like the option that you have chosen. it works great for me.

The 1-2 accumulator spring is not replaced in the trans-go kit. It reads in real big letters to resuse the SHO spring.

I wish you were closer. I would have loved to have the oppertunity to show you what we can do.

I need help please.
I just called the tranny shop to get an update on the progress. I dropped my car off last Thursday btw.
Apparently, they cannot find a new TC for the SHO. SO they had to send my old one off and have it rebuilt. This is going to cause me a delay. Rental car fees on top of trans. rebuild cost is outrageous. Does anybody have the p/n or website info. where I can get one? If I overnite one, it might speed things up. Also, assuming I can't get one in time, how dependable will a rebuilt TC be?

 

[SHOZ123]

Rebuilds are better than the originals. But they usually need your core.

 

[Silvapain]

A rebuilt, fully brazed aftermarket TC will be more reliable than an OE one. I'm not surprised that the shop couldn't find one - they are specific only to the V8 SHO.

I wish I could help, but I don't know any place that sells a V8 SHO TC.

 

[SHOZ123]

If you go aftermarket and do not provide yours as a core then you will get a V6 SHO TC. Which is still better than OEM.

I have one that is suppose to be brand new from a FPS tranny you can have for the cheap. But I personally would not use it except as a core.

 

[SHO#7]

I can build one if needed. But I too will need a core. Just used the last ( actual V8 ) one I had in stock...

If you get stuck let me know.

To R and R a TC should only take a day or two.

[DavidT]

thanks for alll the replies, you guys are great
I will just wait the extra day or two while the OEM is rebuilt.
If a year from now, or even two, OR even a few years... the tranny goes boom... I am moving to Ohio or Atlanta I really wish Mike or Doug (a reputable SHO-knowledged shop) could fix my car. Oh well, who knows, this shop here in town might do top notch work... I sure hope so.

 

[DavidT]

I probably should start another thread, but...
I got her back today. Rebuild, including rebuilt TC, and a transgo shift kit. I just reprogrammed the computer with Doug's XCal tune. Is there a break-in period (do I need to be gentle with it)?

 

[Silvapain]

When I got my car the tranny had just been rebuilt, and I was told to not put a tune on it for the first 100 or so miles.

 

[SHOZ123]

If you have gone to the 3.98 gears you will have a tune in it from the start.

There really isn't that much difference with the normal tune.

Also, I am now seeing some real cool tranny temps (with the rebuilt tranny AND the gen.2 cooler/radiator bypass). This morning after my 25 minute drive to work, the trans. temp. was 125 degrees. Can spirited driving at this temp. be harmful to the tranny?
btw, prior to the rebuild, the trans. temp. was 180 degrees when I got to work...

 

[Ian Macoomb]

I used to beat the crap out of my car right out of the driveway. I drove the car hard from day 1 that I had that. That was in March of 2001. I put nearly 90k miles on the tranny (about 136k total) before it started to act up. My second one didn't last nearly as long though POS Gen 3.

I usually see temps up to 150F. On hot days (90F) it will get up to 180F. On the track up to 225F.

The tranny is not like the engine oil with the water contamination from air that is being used in the combustion process. The fluid should remain free of water so the need to get the temps above a point where the water will be driven off is not there. You will be OK and the fact that the tranny is cooler is a bonus.

Never have beaten it up at all, and have only taken it to the track once. Seldom use WOT, as it is actually a bit quicker under most circumstances at just less than that, it seems to me, and always let the engine oil temp and trans fluid temps come up from cold before hard throttling. Currently at 175K on original transmission with zero problems. Absolutely great Gen 3.
