Gen V on a 96 [fixed] Empty
PostSubject: Gen V on a 96 [fixed]   Gen V on a 96 [fixed] EmptySat Jun 26, 2010 4:12 am

As some of you know, i bought a generation V supercharger, did some crazy hand polishing on it, and installed it this past week (6/23).
For the record its a HUGE difference between a ported gen 3 and a ported gen V. I did some reading and with mods people are seeing 20-25 WHP gains from the swap alone. It feels like every bit of that.
I do also have a 3.4, 1.84 rockers and a 77mm N* (which matches the port job to .05mm and i did it without a micrometer or a 77mm TB/plate to compare it to wink

The car pulls very well, and i think after installing the headers i just bought i can tune out the KR i'm seeing now. There are 3-4° now and i had 0 before the swap...must be the 13psi in 98° FL heat.

My problem is the transmission is now acting up. Yes i do have 170k miles on the car, but it was all fine and dandy the minute before the swap.
I believe i have something set-up wrong with the vac lines that run to the tran shift solenoid because when i first went for a test drive it slammed 1-2 shift at very low throttle %
[1996 rivs have a vacuumed controlled shift modulator that runs off a vac tree found only on the gen 3 1996 blower for anyone not aware of year to year changes]

I did turn down the pressure in the modulator all the way and it still shifts much faster than before. It's probably similar to a shift kit on a 97+ car, which i dont mind.

However, on the highway when it gets warm, OD is slipping and with cruse control on 70mph the rpms will start off normal then slowly rise as the trans temp gets up there. It was at 2600rpm at 70 Gen V on a 96 [fixed] Fresse
SES light came on and it was code P1870. This is a vin specific code from what i gather and it could mean a host of trans problems, some of which include harsh 1-2 shifts, internal shorts, and component slippage.

I need HELP. Anyone know how much vac the trans should have to operate normally? i had to make a custom vac setup to work with the Gen V and in doing so i reduced the hose diameter and ran it different than OEM.
Anyone else do a Gen V swap on a 1996?

Thanks,
Matthew

P.S. i know this is for a different thread but i'm seeing spikes of KR at shifts (12°+) and i'm hoping that will go away when i fix the trans and that it's just false KR from shifts.

The factory config for the trans line has it going to a large port right behind the TB then going to a second smaller port on the tree.
in my setup i have just 1 small line going to a large port on the "tree" point of the gen V. not sure how i can add a second larger line right behind the TB, if it's even needed there.

Oh, and how can a shift modulator affect trans slippage? should i change the filter and fluid? it's a year old w/15k miles but i used dexron VI

Did a ton of reading and researching here and it looks like i may have the PCV setup wrong.
The port i am using for vac on the trans and the BBV is supposed to be used for the PCV system. While it does have vac and puls in lots of air, i think something must be happening when it gets hot and the pcv system changes somehow.

c'mon guys, i hate talking to myself here lol

Any reason why i cant run a T from the LIM port on the snout side and run the FPR off that? isnt that how the 97+ L67 cars are setup?

I thought the Turtleman and others had all the pic's of what went where, when it came to swapping the Gen3 to Gen 5.
I don't think he had the vacuum trans, but maybe. I don't remember much right now, but I do remember him posting some mods made to the Gen5 he has had for a while, regarding the PCV and vacuum changes he was to do before install.
Might want to search for post's or try and get a hold of him.
Also, don't know where BillBoost is spending his days, but he is another source of knowledge.

I am all washed up as far as knowledge goes for now.

But, I know that Derek, deekster and BillBoost have worked on many years and models and have solutions to those problems.
If your really in a bind I'll try and find Bill's phone Number for you.

Bill should know since he has probably worked with a few 96 SSEI's in his time.

Ok, i changed a few things and on short drives it does fine. the trans shifts really slow like factory buick, even with the modulator turned all the way up.
here is the current vac routing, i plugged the port on the blower and ran a breather. i'm guessing the port is for pcv only and can not be used as a spare vac port for other things?

I am going to take it out on the highway and see if its still slipping. If so would this mean just a new TC or a full rebuild?

If your Trans problems just showed up with the install of the GEN V, then i wouldn't be so hasty to condemn the trans yet.
There are changes that need to be made to accommodate a N* TB and your PCV valve as well as possible other crankcase ventilation. IDK. I'm forgetting a bunch that I've been told regarding this. Some internal drilling to allow vacuum movement, etc, etc.

Just don't run it, if you can avoid it until you talk to someone who knows.

Just my $0.02

With the way i have the vac lines routed now i have not had any more SES light, BUT i have not taken it out for a long drive yet (>25miles) with cruse on 70 like before.
I am going to add a bottle of Lucas stop slip and see how it does Tuesday on my way to work.
I'm also seeing less KR than before, which should be all but gone after header get in.
I would ideally like to run the trans on its own vac source so i can have firmer shifts and not have a slippage.
How many things can i run off one vac port before i start having other issues?
And my last question is how are the stock L67 vac lines ran?

There is no answer to this question. Too many variables.
How large is the source and how many things are attached and how much does each thing demand at full operating needs. It' like asking, How many flowers can i soak with this one garden hose.
What's the diameter and length of hose, what's the water pressure, how thirsty are the plants.??????



And my last question is how are the stock L67 vac lines ran? Somewhere archived on here is a vacuum hose routing diagram for the Series one and 2 engines. I've seen them but don't know where.
Good luck and don't blow your trans till you figure out the remaining stuff.

I know there are vac routing somewhere on here, but i have been unable to find them. the only ones i've found so far are pics of MY engine or other 95/96 engines which doesnt help me.
I also have a 97 FSM (i know, i have a 96 but it was given to me) but it has no listings for vacuum except "vacuum brake booster".

There are a shitload of posts all about vacuum routing with pic's from all years.

yea that's for a 96. the 97+ have a different routing b/c there is no vac tree or a vac controlled transmission.
i need a pic just like that for a 97+ riv.

Just got back form a drive and i've got a P1441 code now frown
"evap purge during non purge conditions" WTF?

It would appear you have a vacuum line hooked up incorrectly based on that code.

The EVAP system was in a non-purge mode when it sensed vacuum, is the way I read that.
But I would have to have the book for your year car.

OK i'll go play around with the lines some more. it looks like i can run another T at the FPR to go to the BBV solenoid and free up another port near the evap/trans.

Have you had to make any wholesale changes to the PCM for the GenV and all the rest you have changed, or has it been just a little at a time.?

That's what I was wondering. Whether the car started and ran OK after changing the SC's.
Other than the Vacuum issues, that is.

I don't think I need to ask you this, but you have checked all your rubber vacuum hoses for any cracks and sprayed for leak detection.
