Guys,

I know dimi108 got the 6 cylinder shift kitted, but I want to know if the astron can be shift kitted too.

Benefits, downfalls etc... please discuss.

you probably could. don't know who'd do it, but you probably could.

My friend has a shift kit in his VR commo auto. The thing holds first gear as long as it can and gives a mighty jolt when it changes. To be honest, it kinda ruins the ride for passengers. Not a fan. I'd imagine it wouldn't be too kind on the already crappy TR auto anyway.

Then again, it might become a friend if you understand what I mean.

hmmm stagma being the electrical guru (well compared to me) was looking at this about a year ago. But never followed him up to see how he went, but i know it was being a real pain in the ass to work out. So maybe shoot him a pm and see what he says.Not sure if he still comes on here.

Assuming the 'shift kit' is a resistor mod to increase pressure in the box, dont bother.

I had one in mine (ford), and although it was fun, the box gradually f****d up and wouldnt engage the appropriate gear when flooring it......

Is that all a shift kit is? A resistor? :shock: How would I go about cooking one up? I have a spare auto gearbox on hand if I break this one...

Find the Sol B wire and throw a resistor on it I think.

A true shift kit is not "just a resistor"....it is a true modification to the valve body....

A shift kit will also reduce wear on the transmission....not harm it....

Honestly....you guys talk so much **** sometimes.....

I am aware of this :nuts:

I thought i'd bring up the resistor mod because basically thats what every is running when they talk about shift kits, because not many people wanna spend the money to do it properly with modified valve bodies and such.

Giving him advice NOT to do the resistor mod is all i did...... Honestly your so full of s**t you think your clever to make stupid comments like that.

Was I even talking to you mother****er???

:js:

Calm yourselves children, if we want to play together we have to learn our manners.

Chuck, can you please explain the modifications to the valve body and how it affects the gearbox? Would a resistor (variable maybe :D ) work decently in its stead?

Someone in the 1st gen forum did this a while back, has a good write up if people are interested.

An electronic shift kit works well on some cars, not so well on others. If the 2nd gens use INVECS adaptive shift programing, you might find it hard to get an electronic kit working. People who tried it with the 3rd gens found the TCU would compensate for the change in signal output to bring the shift strength back into factory limits within a few mins of driving (the TCU learns it's way around it).

Works very well on one of my cousins AU falcons. It's allows him to switch between a self adjusted (via POT) shift strength or factory (bypasses the kit). On the firmest setting the car will chirp when shifting into 2nd with a noticeably hard shift. For everyday driving he lowered the shift strength to just above factory smooth for better fuel economy, and interestingly lower gear box fluid temps (he measured), since the box doesn't slur the shift as long.

Lucifer,

You can come close to replicating the results of a shift kit electronically. However, going with this method (such as a resistor) you will only be changing how hard and when the gears change via signals....

A true shift kit actually makes the car shift from one gear to another, whereas a normally operating automatic transmission will upshift in 2 gears at once. This helps in keeping shifts smoothe but causes alot of heat....and that will **** your transmission up.

If you want to go the electronic route....dpack_1 put up a diagram you can use to make your own...

Understood, thanks for the link there. Given the increase in heat, would it be adviseable to upgrade my transmission cooler? What benefits would I get from the electronic route? I gather I'll be able to hold my shifts longer, select gears almost manually etc...

"IF" you did the resistor mod, the shifts seem quicker and almost thumps into the next gear, it does feel faster but many people have tested before and after on the 1/4 mile and found no difference...... im not sure about benefits in the proper shift kits, id assume there is benefit as alot of drag cars are running them...

The resistor mod is something you switch on once in awhile as it makes for really uncomfortable driving when cruising around town as it tends to slam into the next gear even when going slow....

The adjustable pot idea is the prefered option as you can adjust it till its nearly off but just enough to make shifts firmer, then at the drags you can crank it up

Dude settle down.

One: I said "i think"
Two: It's sol A in a first gen, and yes, you can just put a resistor on the wire, it will make the car shift firmly, it may not be a mechanical shift kit, but it's still a shift kit.

Don't get your nickers in a not so easily, you only look like a moron.
