Happy New Year all! Let's keep this board alive for 2021.

Same. While having my GTP from 02-14, I built it for a buddy in 09 and bought it from him in 16. Going all out now while we're still on partial shutdown. Great way to pass the time.

Welcome back earth1. I'm still sticking by my project regal, even if it has been a garage queen for the last couple of years.

@  earth1 : (18 November 2020 - 03:27 PM)

I want to thank those who run this site for their dedication and for keeping this site going through the years. To have a really good Regal GS, one has to have an extraordinary level of dedication to the car that includes a long-term commitment to it, and not just a passing fancy. Similarly, to the people that keep this site going through the years had to have a similar level of dedication and commitment to keeping it going. I just want to tip my hat, pay my sincere respect to this level of commitment, and say thank you. I will try to contribute what I can. I know that these cars are 20+ years old now and a lot of people have moved on from them, but I want to be counted as one of the ones that stuck with them for the long-term. I hope to see others that love their Regals be active here in this site, and for the Regal community to support each other. Count me in.

I finally remembered my password and can get logged in. I have missed posting to this forum. Lots of things to add here from my own Regal GSE project.

@  ejguillot : (20 October 2020 - 03:32 PM)

Well, welcome back!

Sucks these forums are as vacant as they are... oh well, there's still the faithful like us!

@  kevandkaye : (27 September 2020 - 02:40 AM)

Yet still, we lurk. :o

@  ejguillot : (27 September 2020 - 01:08 AM)

Yeah, Facebook took over and killed forums.

@  dezldave961 : (26 September 2020 - 03:24 AM)

Ya, most of the original wave of active members have changed vehicles to something (probably) less mod-friendly, with the occasional person in an LS or Hemi that they do some bolt-ons to. Kinda sad that forums faded.

@  ejguillot : (23 September 2020 - 09:02 PM)

Finally updated my signature to match my current Buick.

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.
