Default Have some converter questions...

OK, just some random thoughts since I will be getting a ST3500 in a month or two. I'd like to make sure this is really what I want.

1. I'm going by the +1 rule, by that I mean I've heard it said to get the next stall up from what you think you can handle, and I think a Vig2800 would be perfect, so the next up would be a ST3500. I'm sure the stall won't bother me, but I have other concerns.

2. Reliability. I'll be running a B&M tranny cooler, but that will be it. Can I expect my tranny to crap out on me in a year? In two years? This is my daily driver, I'm a college student, and I need this car to last me and be reliable. The car gets taken to the track twice a year, and in one year, I probably put in around 10 passes. Otherwise, my daily driving is fairly tame, but I do give her hell about once a day, maybe a bit more if I'm feeling like it <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Regardless, I don't have the money to dish out for a new tranny should this one go out, so I don't want to sacrifice reliability for a little performance. BTW: Car has 63,000 miles on it, half of which I was behind the wheel (read: semi-abusive driving <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> ).

3. Should I pick up a TransGo shift kit? I know Yank recommends not running one, but the TransGo doesn't raise line pressure as far as I know. I'd actually think it could be benefitial to the longevity of my tranny, but I'd like to get some back up on this. Also, if I do run one, what washer setting should I use?

4. Performance from a roll. I know converters are all about your 60', but I also know they give you shift extension. Will this stop my car from fallin on it's face on the 1-2 shift? Also, will it have any effect over a stock converter at WOT on the 2-3 shift (will I still get shift extension even though I'm going around 95mph)?

5. Should I also invest in some custom tuning to get torque management deleted? I'd think torque management would help to prolong my tranny, but then again I don't know alot <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

So, if anyone can address some of my concerns and questions, I'd greatly appreciate it. Thanks for any help guys.

1) Good rule and you have followed it wisely.

2) A converter does increase wear as the tranny sees more torque. Lots of guys need rebuilds by 60,000 miles, so you may already be on borrowed time and converter will not hasten the need that much.

3) some people believe that a quicker shift will reduce clutch wear. I don't think it is proven although the idea makes some sense. Overall, most people get them if the shift feels too slow or sloppy; otherwise they leave it alone.

4) Yes, the shift extension will help from a roll by providing torque multiplication on the upshifts. ST 3500 will hold around 4500 rpms on the upshift. With 3.23s the gains will be over by 100 mph in 3rd.

5) Torque management is designed to reduce the torque during the shifts. Deleting it will increase the wear on the clutches. I have eliminated it only for WOT shifts.

Thanks for the detailed response, I always love to learn. One thing..........

</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">So basically if I get the converter, I better have an emergency stash in order to rebuild the tranny or get a new one right? Is Speed Automotive the place that sells wrecked F-Body parts? I might go ahead and see how much a fairly new tranny will set me back before I go ahead and put a converter in. This could definantly put a damper on the wheels I want this summer <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> Oh well, we will see.

It's not like the converter is going to kill the tranny overnight, but a reasonable inference is that wear is increased, although I've never seen it quantified. Any time you mod your car and make more power, you increase the stress on the rest of the parts. Therefore it is a good idea to keep in the back of your mind that things might need fixing more frequently.

Wearing out clutches is not the same as trashing the tranny, so even if you ended up needing tranny work, the better solution would probably be selective repair of your tranny rather than buying an unknown junker.

BTW, There's nothing to say that your tranny won't go for 100,000 miles. Just the combination of a lead foot and extra power frequently shortens the life of a tranny. A good cooler, like a 19,000 GVW B&M Supercooler, is a good start to protecting it.

First off, LMAO at your title under your name, "Topless Director." Second, thanks for the help man. The only concern I have is that I live in TN, and have yet to find someone competent enough that I'd trust them working on my tranny. I do plan on getting a good tranny cooler, which would be better, the B&M 19,000 or the 24,000? Also, most of my miles are interstate miles so that should keep wear down a bit as well. And when worst comes to worst, I'll just find someone, somewhere that can replace the worn parts instead of going for a whole new tranny. Thanks for all the help Ragtop, If I drank, I'd <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> ya <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I bow before your wisdom <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" /> Raptop 99 LoL, thanks man.

Your killing me. <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" />

normally the 19000 is fine except for autocross. The primary downside to 24,000 is that in the winter it can take a while for the tranny to warm up to operating temp. Lock-up won't kick-in until the tranny reaches a moderate temp. Depends on how cold it gets in the winter.

I'm sure the 24k is a bit bigger than the 19k. Ummm, like I said I live in TN and it gets kinda cold around here, down in the teens, and it does get hot as hell (up around 100), so which do you think I need? Is there a way I could get both and just exchange the 24k or the 19k during the cooler months? That's why I asked about size. I might just get the 19k and be set with that. I'm psyched about getting it already. I just scored a posi and 3.42 gears for $75 so those will be going in too. I am sure I'll need ET Streets to hook it at the track now. ST3500 and 3.42s, I can't wait to go for that ride <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Hey, since I'll have shorter gearing, and that will in effect make the converter feel tighter and not slip as much, could that help my tranny live a little longer? Just a thought. Thanks for all the help and any more man.

I just had a ST3500 w/shift kit 3 washers and 19,000 tranny cooler and a race prep rebuild done. Damn that is a lot. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> All I can say is "It is one badass setup" <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Here is a link that might help you out. Read the whole thing. You might want to wait until you can rebuild the tranny before you get the converter in. Here is the link.

I'd go with 19,000 if you see temps in the teens. come the summer if you are running hot, a 160 T-stat (I assume you'll get a HPP3 for the gear swap and that will let you change fan settings) will knock the temps down some more.

The gears will definitely make the converter feel tighter. ST3500/3.42s will make a very nice all-around combo.

You may be able to hook on nittos (I did at tracks with good prep) and not need the ET Streets. Just don't go busting the rear now. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Alas, my converter may get put on hold for ANOTHER FREAKIN YEAR <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> <img border="0" alt="[whiner]" title="" src="graemlins/gr_cry.gif" /> It's partly my decision though. If I get a converter, I'd like to make sure I get everything right, including having money left for a rebuild if needed. As much as I'd like to have one this summer, my girlfriend and I are planning a trip to Florida so my extra money will most likely go to that. It's good and bad. My car is still under warranty as well so waiting until next summer might be best really. I'll go ahead and do the gears, and get everything done besides the converter. It really comes down to either getting new wheels or getting the converter, and I'm wanting to make my car a good all around car, so I'll most likely end up with 18" Y2K polished vette wheels and Kumho tires. In the event that my extra money can't get that, I will get a converter and cooler for sure, and if money allows, 2 extra wheels and some BFG drag radials. Only time will tell though. So even if I can't get the rims, at least I'll be going fast enough to not really worry about it <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Really it's hard to lose either way.

Do you want to be SHOW or GO?
18" wheels might help you in autocross, but a set of nitto drag radials on your stock rims will give more grip than 18" Kumhos. Use the nittos in spring through fall and put some all seasons on for the winter.

LoL, ALL SHOW, NO GO!!!!

Actually, after watching those F-Body Hideout videos, it's got me wanting performance. But, I think I'd get more smiles/dollar from the wheels. I mean I can enjoy the converter when I hammer on it, but I can't do that everywhere otherwise I'll be buying tires and getting pulled over all the time <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I could just look out the door and see my car lowered on polished 18" Vette wheels and say to myself, "Damn, I've finally got a car that looks completely badass." It really is going to come down to money, because the wheels and tires might be a tight squeeze, so I may have to just get a converter. Not sure though, we'll see I guess. I'm going to go ahead and lower the car and do some suspension stuff (APHR, LCAs and reloc. brackets, STB, Eibach Pro Kit, Bilstein HD shocks) and then we'll see where it goes from there.
