Yikes, well hope you guys get that resolved, so it stays active enough to remain viable.

the sign in process is broke because the captcha is non-functional. That is why no new members.

Somewhat true, but I'm not going to get too real about the demographics of Regal owners past & present. It'd be out of place on a Regal forum, and make people cross-eyed coming from a Regal owner. :blink:

@  Marchi1 : (28 April 2021 - 06:34 PM)

we are also hitting another round of buyers...and the group is again the young crowd and realizing that the older Regal is a bargin and normally better maintained than the GP of the saemarea.

Hey, that's where I buy my top-of-the-line Spectre intake parts for my hotrod! (pre-turbo)

@  alemstrom : (26 April 2021 - 11:33 PM)

I'm here at Advance Auto

We're now in a preservation community that some may discover, but it's been spread thin and the traffic has shifted away from the initial sharing styles (Tim/Zoom discuss this on ZZP podcasts, when those 4cyl goobers let them talk).

@  dezldave961 : (24 April 2021 - 02:20 PM)

The vehicles themselves dictate the demographic and activity level based on their following. GTP's drew the majority of the L67 crowd, including myself, and current 4/6/8cyl offerings of the last 15yrs are where 99% of our former peers and newcomers have shifted to.

@  Marchi1 : (21 April 2021 - 02:25 AM)

There are a few who come here for the info.....

@  dezldave961 : (19 April 2021 - 10:57 PM)

Ya, 3800/Wbody forums have cleared out. I hear there's some FB groups, but I'm ont on there and it sounds similar to the newbie-centric folks I see the last 1-2yrs on 3800pro & GPF.

@  glendayle : (18 April 2021 - 03:59 AM)

Man this thing used to be hoppin' on the daily. How times have chagned.

@  glendayle : (18 April 2021 - 03:59 AM)

LOL, someone chatted?!

@  dezldave961 : (17 April 2021 - 02:04 PM)

Just keeping the candle lit, as I mentioned on my only remaining local ClubGP chapter of the 3-4 I was very active on in my 20's

@  Marchi1 : (15 April 2021 - 07:00 PM)

nope...just us old timers

@  WildGS : (15 April 2021 - 03:56 AM)

are people still here?

@  dezldave961 : (12 April 2021 - 09:46 PM)

Hey, chuggin' along. Just finished a big overhaul on my turbo build after 12yrs.

@  Nateteo : (12 April 2021 - 05:56 PM)

literally, the last time I logged in was 3 years ago hows everybody doing

@  dezldave961 : (12 April 2021 - 04:43 PM)

Ya, they do open bracket at GS Nationals. I may go if I'm free, just to attend, even if there's no cage, yet.

@  Marchi1 : (12 April 2021 - 01:32 PM)

I am taking the SC car.I am sure it is a big event as it is in Bowling Green, KY so yeah will need to be fully copliant, but I think there is a bracket class. God I hope so

@  dezldave961 : (08 April 2021 - 01:50 PM)

*S&W Racecars cage for 95-99 Monte... I'd actually fit the xTSM class, aside from not being a RWD, if I swapped the Air-Air I/C back in. Probably wouldn't be competitive just yet, but I'd like to see them squirm.

I had the stock 4T65E of my 2000 Regal GSE rebuilt and seriously upgraded in 2012 but I never did post the details of that upgrade to this forum and I wanted to go back and do that. I am VERY happy with the results and it's worth sharing what was done, and that is the purpose of this post.


The work was performed by Max Speed, Inc. which is a franchise of Speedy Transmissions.

They are located at 850 Sandy Plains Road Marietta, GA 30066.


When I took the car in, the predicable missing 4th gear was the main issue. 

I specifically requested that they "Beef Up" the transmission. I said I wanted them to make it "STRONG", and to apply any upgrades as they would if this were their own transmission. I made it clear that I wasn't worried about the price, I just wanted this thing "STRONG". The following is a list of what was replaced/installed, as dictated from their receipt to me:


Billet Converter

Transmission Filter

Master Rebuild Kit


Pressure Control Solenoid

Shift Kit

AFL Valve

Kevlar Reverse Servo Band

Kevlar Forward Band

Kevlar 1st & 2nd Clutch

4th Gear Clutch Shaft

Sun Gear Shaft


Parts total was 2109.87

Labor total was 994.78

Total amount paid in July of 2012 was 3131.24 including tax.


I drove the car until 2014 and then stored the car for 6 years and I just put the car back on the road about 2 months ago so the transmission has only about 2 years of use on it. Indeed it IS strong now, and a worthy transaxle for my 3800. I can no longer say that my transaxle is a weak link at all. Also interestingly enough, the car does not "torque steer" as it used to before the rebuild which is a nice change. To date, I have never had any further issues whatsoever with this car's 4T65E. 

Hopefully this list of upgrades will serve as a useful reference if anyone out there needs their stock 4T65E to be upgraded to something strong enough to be worthy of their 3800 L67. I couldn't be happier with what Max Speed, Inc. did to mine.
