Has anyone installed a B&M shift kit or TransGo kit in a 700R4. How much of a difference did it make? Was it worth it?

 

I installed the B&M kit in my car, the shifts were faster and harder (since I got a v6 its not that much of an improvement). I basically makes the car feel like it got something wrong with the tranny. when people ride in my car I usually have to explain why the car does that (especially to women)

 

Do these harder shifts put more stess on transmissions?

 

I'm not an expert (really i need help myself (more than trans help i think))

But i would assume the harder shift would definatly prolong the life of the friction materials (the first to wear out), but decrease the life of the hard parts (splines, thrust washers, bushings, planetarys.......) slightly.

I would recommend a kit anyway simply because of the above..

dont get a kit, get a vette servo and .500 boost valve.

 

what ron said, thats all you need to get firm shifts.

Hey Man I got a B&M Stage 2 Shift Kit in my 89 IROC 305 TPI 700 R4. The difference is harder shifts and more torque form 0-60 , not that the 305 doesnt have enough it jsut puts it almost to the edge. I've read about the corvette servos but not sure what the deal with them is? Are they expensive? Just wondering, Hope my opinion counts.

 

Goto http://www.hptransparts.com They have a vette servo, .500 boost valve and new accumulator pistons package for less than $20

 

Which is easier to install a vette servor and boost valve or a shift kit? I have heard that shift kits prolong the life of some of the transmission components, is that true and does the vette servor and boost valve help my tranny live longer?

 

C'mon, nobody has installed the vette servo in their car?

 

In my opinion they are approx the same.

You change the pressure valve in both. This doesn't require dropping the valve body.

With the shift kit (most like b&m) You install a metal pin (1/8" diameter x .890" long inside the spring, or ditch the spring and put a 1/4" x .890" pin in) instead of a spring in the line bias valve, put bushings instead of springs in the 1-2 and 3-4 accumulators (the same thing can be accomplished simply by putting the piston in 1st, and put the spring on the other side), remove the 4-3 sequence spring (put nothing in its place), and drill a hole bigger in the sep plate. You even can get the instructions from B&M for free on their website! Ok so basically B&M shift kits are a bix box filled with junk and a higher pressure valve in it. Pretty expensive valve!!!

I have a box of the blocking pins (free, a 5/16 bolt with the head cut off and sized works fine), all you need is the drill bit.

With the money to spend on a b&m kit, you can get the vette servo, .500" boost valve (the highest), and they throw in new accumulator pistons for free. Then you have enough change left over to buy the drill bits. So you can do both if you want at no cost, or do the servo and not drop the valve body.

But, the tradeoff is you must disconnect the mount and pry the case over enough to get the servo guts out. Lowering it is a possibility, but noone I know who did it had to. Getting access is a little difficult (because you can't really see).

P.S.: Not all kits are like the B&M

 

That's not true..

A true shift kit doesn't just drill a hole here or close a hole here. It actually changes springs in the valve body too. This is what a TRUE shift kit does. It is not a temperary fix or a small modification to the tranny.

If you are going to do it right, then get a shift kit, but get a good one, not a cheapy one.

Go with the Trans-go kit...
