Re: Rough Shift from 1st to 2nd @ Lower RPM
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.

Re: Rough Shift from 1st to 2nd @ Lower RPM
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

Re: Rough Shift from 1st to 2nd @ Lower RPM
[QUOTE=1986nate;712345]May want to check your math. Last I checked 1997 was only 15 years ago
Ooops! Math and Crown Royal don't mix (but Coke's okay)

Re: Rough Shift from 1st to 2nd @ Lower RPM
Checked my resistor tonight. 13ohms. I guess that's not the cause of my hard 1-2 shift...

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

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. |

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

Re: Rough Shift from 1st to 2nd @ Lower RPM
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. Last edited by Lookin4SVX; 09-26-2012 at 11:58 PM. |

Re: Rough Shift from 1st to 2nd @ Lower RPM
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.

Re: Rough Shift from 1st to 2nd @ Lower RPM
You might go back to the transmission shop and have them do a line pressure test. It sounds like you might have a problem.
