Well I guess it is pretty self explanatory. I am putting in 3.73s next week and I have been doing searches like crazy for this. What I need to know specifically is do I need a shift kit for the AOD when I install these gears? I keep reading about needing something for the RPM extender or for the governor. Can someone clarify this.

P.S. I bought 3.73s because that is what I want. Please no 4.10 suggestions.

I need to know too, i am going to drop my 3.90 rear in sometime and i want a shift kit. I dont think i want a converter, i will have a stock motor and the car is street and daily driven.

How are the kits like B&M shift improver kits??

Well it seems to be pretty unanimous that B&M is NOT the way to go. I hear either Transgo, Performance Automatic or the Baummann kit. I am going to post a poll on this right now.

I wouldnt say necessary, but 100 percent effective...if that makes any sense. IMO, owning an AOD car *without* a shift kit would suck. I'd have put in the SK before i got gears, but that's just me. Get your gears in, and then get a nice stall converter and shift kit...that'll really wake up your car.

You'll need to do a shift kit because with
the deeper gears it fools the trans into shifting at different points.

You can also get a higher rpm governor kit from TCI.

Read up on that at Baumann's site www.becontrols.com and at TCI

Here's some info on beefing AODs

shift kit not mandatory on 3.73's but worth the money to firm up shifts. and it lets more fluid flow so a cooler is good insurance for your tranny.

stall converters are fine for daily drivers and are the best performance upgrade you can do to an auto car.

just dont go cheap on any component when you want performance.
