Does anyone have a TH400/TH350 with an electronic overdrive or gear vender for a 4th gear, for freeway driving/just cruising? With 3:73's I need somethin. Thanks

I know that Injuneer in running a gear vender off the back of his th400, there expensive tho, your probably looking at around 2500 for a unit if Iremember the price right. there really nice but come at a huge price.

3.73's and a gear vendor will solve your freeway problems and also keep the rpm's where you want them while racing. 3rd over with a GV is about the equivelant of having 2.90 gears if i remember correctly. (I worked at gear vendors for 4 years assembling he new units.)

Over drive is over rated, I run 2.75 gears, I don't need no stinkin overdrive LOL
sorry kind of a newb question but i just blew another 4l60e, what exactly does the gear vendors unit do on the th400? i see that it goes on the tail shaft of the trans and somehow gives it an overdrive but when gear vendors sells them is it just the overdrive piece of is it a comple transmission?

The gear vendor is kinda like a transfer case. It bolts directly to the back of your 400. It has a set of planets in it to give you the od that you are looking for. I have heard of guys that engage the unit in every gear and then disengage when they shift to the next gear. Kinda of a cool piece IMO. I to have seen the inturnals of this piece and it is very well constructed. I have never heard of someone breaking one if that tells you anything. Vince.

I just blew my 4th 4l60E (2 Rock On's) and I am so tired of changing that thing out. Time for a new set up. Does anyone know how strong the Gear Vendor is? Approx. how my hp/tq will it take? Can it be built stronger? I daily drive my car so the OD is nice and I'd like to do this once, so I want the best and strongest set up. Anybody have a testimonial on this set up?
