Rough Shift from 1st to 2nd @ Lower RPM

Four small crimp connectors (solder would probably be better, but my iron failed to heat up), Two 3" pieces of 14GA primary wire, and four 1" pieces of heat shrink to make sure nothing shorts....works great, and only took about 1/2 hour to complete.

PS - If you go this route, the wires leading to the original resistor are very short. Cut them as close to the old resistor as possible to make splicing easier/possible.

I'd rather not splice anything if I don't have to. Since mine is a 92, should I get a resistor from another 92? Or should I go for a 97 since it's a later year and probably a better resistor?

Well, even a '97 is still 25 years old. I read in one of the posts that a 25W 27 ohm resistor worked the best (original between 12-15 ohms). All I can say is that the part was cheap, the job was easy, unless you knew what you were looking at it would seem stock, and most of all my tranny shifts beautifully between 1st and 2nd for the firts time since I've owned it . If I could ever locate my camera cord, I'd take a pic for you.

May want to check your math. Last I checked 1997 was only 15 years ago

All resistors are the same spec for OEM.

I have had the same "problem" since I got mine
when cold the shift to 1st is harsh
shift to 2nd kicks my back at low rpm
and `3000rpm it's like a GTR shifting, and anything above that it's like any other auto
and I don't know if you guys have the same "problem" but at anything higher than 3000rpm my 2->3 takes a long time to shift...at +5000rpm it'll redline before shifting (If I don't let go of the gas, which I do a little)
I don't think it's serious...I've gotten used to it

Ooops! Math and Crown Royal don't mix (but Coke's okay)

This is the brake band being out of adjustment. You'll want to adjust it back to spec. If not, you'll eventually lose the high clutch.

Checked my resistor tonight. 13ohms. I guess that's not the cause of my hard 1-2 shift...

which problem were you referring to?
and I have no idea what any of those things mean!
is it a DIY kind of thing? The transmission was rebuilt not so long ago...should I take it back?

did you have to scare me

The part in bold

And it's possible to be a DIY thing, but it is a pain to reach down to the adjustment bolts. Also, if you don't know what you're doing, you could screw up the transmission completely. (not trying to scare you, just anyone should be aware)
If you still have a warranty on it, or even if you don't, check with the garage and tell them what it's doing. It shouldn't have any type of slip if it's working properly.

bold; haha too smart for me
as far as I know it's just a bolt that adjusts it, right?
It had a 36month/36km warranty, but it was 38 months ago so that's no good
I'll call them though
I was kidding about the scaring...thanks for telling me

Sometimes my RPM will flair up about 200RPM when shifting from 1st into second, then 2nd engages rough, but only when going really slow, like under 1500RPM.
All other gears are fine, no flair, quick nice shifts, even 1st to 2nd is fine unless your barely on the gas pedal.
Is this the same issue, a resistor?
Car has been this way since I got it, previous owner had the tranny replaced and it has one them small car shift kit resistor things.

Same exact issue here! Exactly! Any advice appreciated.

I'm the guy who ran ECUtune. I've rebuilt a lot of these transmissions and used to offer a performance rebuilt transmission for sale through ECUtune. When I first started doing the performance rebuild I used one of the two "shift kits" that are commonly available through the transmission parts supply houses for these transmissions. It included a stiffer spring for the 1-2 accumulator specifically to stiffen up the 1-2 shift. We found that with this spring and the stock Transmission Control Unit programming that while driving in traffic you might experience a harsh 1 to 2 shift primarily when 1st lightly accelerating and then letting off the gas. You would start to get some momentum, you would let off the gas because you are in traffic, and then the car would perform a harsh shift right before you started to decelerate. Experience proved we didn't need this spring and I developed my own set of valve body modifications so this was only an issue in maybe the 1st half dozen transmissions I built. It is very unlikely your car has one of these transmissions. If it did the owner would have been very clear about it and adamant that his SVX was worth more than others. It is, however, very likely that the transmission shop that rebuilt your transmission would have used one of those shift kits which includes that spring.

I also offered a performance Transmission Control Unit---TCU. I don't have them listed on the Subiechips website yet but I do still make them. You can email me to arrange getting one. The shift maps in the performance TCU eliminate that annoying shift into 2nd after you let off the gas in traffic altogether so you can keep your stiff 1 to 2 shift without being beat up in traffic by it.

Anyways, I have no idea who to ask, so here it is. The tranny was replaced at around 70K but I've noticed as I drive it that the tranny shifts VERY rough if it's going into 2nd under 1700 rpm (Thank you Los Angeles Traffic), semi-rough from 1700 to 3000, and smooth above 3000. I've checked the fluid and everything looks good. Is this normal?

You might go back to the transmission shop and have them do a line pressure test. It sounds like you might have a problem.

gee wiz......

I just realized this thread was resurrected from 2 or 3 years ago.ugh
