New 2nd gear for 4T60e?

[Money pit Beretta]

I thought you had the W body trans Isaac. Also I thought you would have it in by now. Thanks for the idea! I'm sure that I'll be much more happy with this trans.

[IsaacHayes]

No, I haven't picked it up yet. There are several at the place about 70miles away. All close to 40k or so.

Been too busy to do much on the car, and when I have a free day I usually want to relax or get outside for once.

[Money pit Beretta]

I understand Isaac. I did hope to get some tips from you on this though.

Ok, my eyes are not as good as I tought, or I was just seeing what I wanted to see in the info chart. My VSS is 29 and the W body has a VSS with 30. Sounds like the speedo will be off. Is there any way to combat this problem?

I'm sure it all comes down to pulses per mile. If it's the same PPM then the stock speedo could read the W body VSS. If that is so, then I will need to buy one.

3X00 can you shed any light on this?

1995 the ring is a 29 yes, but you can run a 30, and its only 5% difference. The W-body VSS will change nothing the speed is calculated by PPM and thats determined by the ring tooth count. You may be able to press off the 29 ring and put it on the new trans... I know some differed in diameter but I think a 95 and a 96+ you can interchange. I say 96+ since even the 95 and 96 beretta they tooth count changed from 29 to 30.

[Money pit Beretta]

Thanks for all the info! I'll have to wait until the trans gets here to see if I can get the gear off myself. If I got it straight, I need to count the teeth on the VSS that is on the trans I have now to be sure how many teeth it has.

Ok, looks like my friend over tightened the valve cover bolts on both sides when we did the intake swap. The back side valve cover has been changed(there was a crack by one of the lower bolts). I will check the VSS when I do the front cover on Sunday.
The trans builder called me today. The tech told me that my car may go into limp mode with the new trans do to the gear change. I have never heard of this.

You have a 95 correct?

If so there is no codes in the ECM to trigger for a gear change.... 96 yes, there is a drive sprocket ratio setting that the ECM will get mad at if it doesn't match. (it does math for RPM vs MPH and Gear knowing the ratio and then will say trans component slip if the gear ratio doesn't match)

I swapped to a 3.33 setup a LONG time ago before going OBDII on my red car and I never had any issues, still shifted exactly where is should since OBDI.5 is setup to do it by RPM only... OBDII is MPH and RPM you have to meet both, and with a 3.33 or 3.29 swap you wont meet the MPH at the same time as the RPM so you'll hit the limiter... well at least I did the first time after my harness swap.

You can throw a Buick Century 3.29 trans in there with a 30 tooth tone ring and drive it all day long, but just remember you are about 3-4% off on the speedo, and mileage readings... they will be higher than they should.


You probably had plastic valve covers correct? If you get the 96+ metal ones then you'll never crack another and you can tighten them down all the way.

[Money pit Beretta]

You are very right, it's a 95. I thought that my computer was set up that way. Well, I thought that the computer only set the shift points. I didn't know that OBD2 did all that. Great info and great help again 3X00, thanks. I feel much better about what I'm going to do. Boy am I glad I didn't change to OBD2 like I was going to.
Yes, the metal covers are a good idea. I will have the plastic ones until they crack again or I build the new engine. When I got the JY plastic ones I also got some metal ones. I didn't want to mix and match and didn't want to redo the rear that I just did.

Whats wrong with OBDII... I did it because I can tune it... I made the changes in the ecm, flashed it and now it shifts better because I fixed those gay ass low RPM shifts... lol

[Money pit Beretta]

Nothing is wrong with it. I just can't tune it and don't have everything needed to make the change. Wish I did though(not enough money).

[3X00-Modified]

Well then thats a different story.... I don't like it when people come out with the "Glad I'm not OBDII because I can't tune it." stuff... Its more like I'm glad I have a PCM I can't tune period so then I don't feel as bad as having one I can tune but can't afford to.

There is too much miss information floating around about OBDII and beretta's and ability to tune and what not... There are two options out there DHP (Used Obviously), or HPTuners (New but you need a 97 Monte Ecm to start)

Looks like the trans for me is on hold. The high frequency vibration with speed felt in the steering wheel turned out to be the new wheel bearing I replaced less than a year ago! The stud spun inside it so I couldn't get the lug nut off. Had to drill it out and just replaced it with a Timken (made in USA) bearing instead and noticed it felt dry when I spun it by hand and made a noise. Went for a test drive and the vibration is gone.

I still have a shake that happens sometimes when accelerating, the wheel vibrates up and down. It usually is at low RPM under load, but sometimes when WOT from a stop too about mid-range. More so I think with the wheels turned. It may be the replacement CV axles are not very good...

I'm sure I could benefit a LOT from a fresh trans especially higher stall and FDR. But I have other fish to fry right now so big projects are on hold. Maybe when I get a house to park the car and then swap motors/etc I can do that or a 5spd. I'd really like to find a rust free car and do a 5spd and turbo with some 3x00 in it. My rockers are starting to go.

Otherwise the car is running good, the BLM's are adjusting to the exhaust. I will be datalogging sometime soon. The low end is crazy now with the larger exhaust. Off the line the car shoots off like a rocket. The top end did not benefit as much. Seems like every exhaust mod always helped the low end, and every intake mod helped the top end... LOL. But it may be that the top end is at the limits of the log manifolds flow. Either way I would expect a gain in the top end. Maybe there is, or just that it needs tuning. I'm thinking about slowly building the adapter to swap to OBD1 ECM from a 3.4L DOHC TDC car, which has the code to run the 4T60-E. I can always swap back to stock ECM during the work week, and swap back to OBD1 and tune etc on weekends...

I'm still going to build a CAI, install a gauge, and swap head units, as well as some paint (shocks black) adjust swaybar, etc so there's still work to be done. Plus I need to update my website and my thread.

[Money pit Beretta]

Almost too much info there Isaac. I don't know how to reply to all of that. I will say thanks for the post and all the info. I'm always happy to hear about what you are doing. I get new ideas and remember others that I forgot about. My shake at WOT may be coming from my trans. There was a good amount of metal in the pan when I did the fluid change(when I first got the car). It is fine at anything other than WOT. That is also why I wanted a new trans(that and the adjustable vac mod is the only thing that makes it shift the way it should).
Your rockers are starting to go? Are they stock ones?
I do read your website from time to time by the way. All that swaping sounds like too much work and I think you may start to hate it after a little while.

Yeah 3X00, I want to be able to tune bad. I makes me mad that I'm not getting everything I could from the top end swap(and other things). I only said that I was glad I couldn't do it because the trans swap will be a plug and play right now and I don't want any problems(DD car). I'll be lucky just to get the trans in before I have to go to work on Monday. I want and need to learn to tune. I have things I want to do to this car and my 04 Cav. My friend wants to tune his 00 Z28 and we plan to get HP Tuners, split the cost that is. When we both have the money(LOL). But that may be for my later engine build. Like Isaac said there are other things I need to worry about first. I can get a Monte ECM, but I'm not sure how that would help me if I plan to do a full 3400 swap later(I was thinking of using the 3400 computer and wiring). We will see, that may never happen and I may just get the Monte ECM.

[3X00-Modified]

I'll never understand datalogging a non tunable ECM... Its like a peep show... LMAO
