If that is true you better get rid of your 727.

I would never question that the kiesler is better...in some ways...better o/d, and it probably upshifts and downshifts more naturally because you wouldn't be trying to split the gears your self.... but not almost 2 grand better. I gotta think that the kiesler is more actual work too. For guys like me who are doing it on their back in the driveway, that means a lot. shifter mods, running new tranny lines, removing the entire trans, changing the crossmember. I think it would be a lot easier to do a gv in a weekend. It depends on what you want too. If you just want to have lower final drive rpm's or if you want to have it shift like a new car.


I don't want to trash them for their pricing. I have a friend who's a GM tech and said that an unmodified tranny isn't a whole lot less than what kiesler wants. If you were starting from scratch and had no tranny, then the GM makes sense. If you already have a good 727, then the bucks say go GV.

Kevin, I've done both GV's, auto and 4spd, plus the Keisler Auto and varous TKO 5spds........the Keisler Auto was just as much work as the GV, what you trade off in work in one installation phase, you gain in the other,....in the GV install, you'll be removing the tailshaft housing, if your working on your back in the yard/garage (bless you) get the car as high as possible, SAFELY!.....youl'll need to "pound"out the floor a little to tuck the GV up in the tunnel, also plan on having the use of an inclination dial/meter to phase the driveline angles, and the possible need for rear axle perch shims/wedges.....when you do the wiring for the control unit, solder all connections, and confirm that your grounds are "solid".....some ignition set ups have been known to wreak havoc on the controller from RF interference.....it's not fun when the GV drops out at 100 MPH plus, and you have 3:91's or 4:10'S!...been there, done that!


The Keisler Auto is not a stock GM unit, many mods, and updates are made to it,....although I do prefer it over the GV's......I'm more intune to recommend the TKO 5spd swap over.....If I didn't have a Keisler option at all,....I'd put a Passon 4spd in long before I'd do a GV again.....just my opinion.....

The Keisler transmission is pretty sweet too as it's like you have a brand new car. Now my only realy complaint so far is i can not get the transmission to stop leaking. It started leaking from the seals at the get go and after some back and forth with Keisler ( )they paid for about 3/4 of the fix. oh well......

I was going to go with the GV but the 4L60E is way lighter and no need to pound the tunnel of the roadrunner. That was my main concern as the shops who have done the GV said they had to massage it to fit. Oh and i was able to have the trans lines rerouted to the Right side of the car and now i have no more issues with my aftermarket shifter cable burning up on the headers!

That was worth the extra $$$$ all by itself.

didn't you have computer issues at first also? that could be a big problem for the back yard kind of guy

Stu,....To me the only drawback on the Keisler Auto was the computer crap,.....did the guy installing your Keisler Auto, interface it with a laptop,.....the transmission line/band pressure/ shift points/ etc are adjustable via computer interface, perhaps that is your seal problem,...to much pressure?

I have to mention again .... for a product that was supposedly made - at first - for the RV application ...why they now don't do a lot of advertising in that area now ..... "says" something to me.

Probably because most all rvs for the last decade or so come from the factory with an overdrive trans already, And people who buy/ own older rvs usually don,t spend that much money modifiying them like an older muscle car.



I used to own a car with the g.v. unit and i,d give it an A+ rating.

Since then i,ve been shopping around for an older motorhome and surfing around rv sites , the consensus seems to be there have been some faluires in rv / heavy trucks applications mainly due to people coasting down Long/ Steep grades with the O.D. engaged and they don,t seem to like that , something about the gear sets don,t get lubed properly while decelerating ??? <-- just relaying what i,ve read. and just thinking out loud here but,,,,,, a knowledgable driver would/should disengage o.d. of any kind going down long grades for the engine braking effect .

What if? seeing it was a new item for Keisler, that the mfg that supplied to Keisler was on backorder?.....Kinda like when Mopar Performance puts you on back order for 6 months
