The Gear Vendors install thread

-
I just updated or installed the new control unit as seen above as the old one had become erratic in auto mode. Have not drove the car yet but the lights and all seem to work correctly. Keeping my fingers crossed after reading the post above.
hope it works well, did GV warranty it? what car is it in and how much surgery was there?

Thanks. Warranty?? Lol. No It’s been in the car 11 years.
73 E-Body so a couple small areas in the tunnel was all that was needed to fit. One for the speedometer adapter was the biggest.
 
Thanks for all the info. There always comes a day when someone will attempt this and the thread is really good.

wow, 11 years, i hope mine lives that long :lol:

ya, i spent months going over this before deciding. not near enough build threads around on these.
 
Was finally able to test the new ECU yesterday. All went well with lights and engagement/disengagement. It does seem to be about 5mph higher in both areas now than previous ECU when it was functioning correctly. 50mph engagement 30mph disengagement. I wish these two settings were user adjustable.
 
glad it's working. i know they don't want it engaging without enough pressure from the pump, so they don't want you going too slow with it in auto.
my new one showed up yesterday. didn't have much time but plugged it in and took a spin around the block. red light works like it should, (lights up in auto mode), but now my speedo is dead :wtf:. no time over the next couple days so i'll look at it later this week. one should have nothing to do with the other so hoping a cable just came loose
 
so, the new controller works. found out the speedo cable issue is the plastic clip on the dash side snapped off. was a brand new cable :wtf:. i will get to that next year...the GV works awesome. just what it needs for running down the freeway. i've also been playing around with manual mode. that works well too.
only had one chance to try the 2 - 2nd over - 3rd - 3rd over shifting, and i blew though that faster than i should have. that's going to take a little practice and an open piece of road :D
also going to move the indicator lights up to the dash some where. i made a quick control panel for them, and the auto / manual switch, but it's not in a good place for keeping track in manual mode.
don't know that i need to use it in manual. i'll probably screw something up and need a rebuild at some point, but what the heck, it's there. may as well have fun with it :steering:

overall i like it. the car definitely needed another gear at 65+. the down side, i had no way of knowing how much surgery was going to be needed before doing this. GV's site makes it sound like a BFH and a weekend will suffice. i know some guys get away with that...but not on my car. i didn't think it was going to be that easy, and it wasn't any worse than i expected, but anyone thinking of doing this better be ready with tools and experience. all together, i probably have 100 hours into this, and 90 of it was fun:)

but,knowing what i do now, i'd probably go 200r4 next time
 
The amount of surgery obviously depends on the car and I don’t believe GV is an expert here. I know all I needed was a few smacks with the BFH but I have an E-Body so obviously the A’s are tighter. Glad it’s working. When I use manual mode I just turn it on for OD. As you have found out, trying to shift it 1over, 2over, 3over is gonna take some practice.

oh ya, i'm not saying GV should in any way know what each car needs. there are some people with A-bodies on here that only needed some hammer work but i don't know what years and body styles. i'm guessing later years Ma tweaked the floor pans and ended up with a little more room. mine of course could not of had the adapter ring at a worse place
 
I reached out to GV yesterday to see if they would provide drawings of the unit with dimensions so I can take some preliminary measurements get an idea of whether or not I would be in for major surgery. I've gotten no response yet but if they deliver I will share in this thread.

My car is a 67 383s 4spd so major hacking of the floor pan would likely be a deal breaker for me.

My question for the FABO Brain Trust is this: I understand that for A-body 4-speed applications a B/E body output shaft is required. Will all the internals of the A-body transmission readily transfer over to the B/E-body output shaft and cross-mojinate happily with the rest of the internals?
 
you can get the install instructions. they have measurements and diagrams
HERE
& HERE
& HERE

unless you lower the trans mount, i'm pretty sure you'd need to hack the floor
 
print out page two and three of the instructions and you will have the templates they supply.
also they are HERE

It is really not that hard. In my 73 scamp with 727 and RB motor, I had to stretch the tunnel a bit. I tried the big hammer, too weak. I tried chaining the car to my 4 post lift and using a jack to push. Bad angle. Then I got out the air impact hammer with a flat blade, I massaged the tunnel in 15 minutes and did not have to remove any carpeting that I just installed. Way too easy. The electronics were simple as well.

That's exactly how I did my 73 Scamp with a 904, SB. Piece of cake.
I removed the electronics on mine I was having trouble with that black box shifting out of overdrive all by itself.

what year is your car? Kent's and Fred's are both 73's, mine is a 68', and the freakin' tunnel necked down exactly where it needed to be the widest.
