Gear Vendor's OD unit
 

Does anybody here have this unit in there car with a turbo 400.What are the pros and cons of this unit and what kind of modification's will I have to do to install this.I will be putting this in a 2000 model Tran-AM.

I think your first issue will be torque arm clearance. We've put one in a viper with a glide but, i've never seen one in an f body.

I have one on my car...there is no TA clearance issues unless you have a front DS loop built into the TA (a la spohn). I had to cut my front DS loop off...

I'll look to see if I can find some pictures.

I would have thought you would need at least a short mount TA and a really short DS.

How do you like the GV unit driving around and at the track?

Thanks for the info. Phate did you get better 1/4 mile time after you installed it. If you have some pic's that would be great.I have a BMR TA on mine will that make any difference on clearance than the sophn.

Are you aware of what those units cost?

Phate might be able to fill you in on that, but I know they definitely aren't cheap.

yes I have been checking out there website and yes they are expensive. But i would like to have OD.

To tell you the truth, after things went together I ended up changing combinations and the car has been sitting a while. I am planning to ship it off and get it finished, but that is maybe 3-4 months out.

So, no track impressions with the GV...but it works as advertised and you can set it in auto mode so that it clicks on @ 50 or so or use it in manual mode.

The driveshaft is REALLY short, I had my Denny's re-sized to fit and it works well. Not sure how the BMR TA is different then the Spohn unit, so I can't comment as to issues there. Sorry that I can't offer more info...but the install was actually pretty simple and pain free.

You want a tough trans and OD go with a built 4L80e. I looked at the gear vendor until I read about the 4L80e.

I have seen a few in 1st gens, but never in 4th gens.

if you drive the car alot, it will pay for itself in no time.

+1 on the built 4l80e. If your set on this route, my uncle has one of these that he used behind a muncie 4 speed (not sure if same as th400), in a 67 chevelle. It probably doesnt even have 1500 miles on it (it still wasnt enough OD for him and the 07 power tour).

Pm me and ill get you a price if you want.

Muncie is a manual transmission.

thank's for all of the info guy's now all I have to do is make up my mind if I want it or not.Sounds like it is what I am looking for.

Im not sure on the difference (bolt pattern, input shaft etc) between a GV OD unit for a th400 and one for a muncie. lol Im not that dumb man.
