hi im still new here but anyways the trans on my 2001 blazer 4x4 has approx. 30,000 on rebuild (167,000 total) and i want to get it to shift firmer to make the clutches last longer (hopefully drum will hold when i do this lol) but to the chase im looking at the b&m shift switch they offer but i can only find it for the 93-98 vettes and have heard they on all the late model 4l60e's work but not too sure......

this is the one i found at texas-speed

any help or other suggestions are GREATLY APPREICIATED!! THANKS!

 

I did a stage 2 shift kit on mine. Hits hard now. Its up for sale though, because its a little too hard with 4.56 gears.

 

I also have one, brand new, never opened. I was going to install it but ended up doing a tune via my HPP3. If you don't want Logan's, being as he posted first, send me a PM. I'll let it go cheap.

 

Hello, you are wasting your time going with a B&M shift kit, they are junk.
If you want your trans to hold up you need to address the problems and fix them.

Dana is the expert when it comes to 700R4 4L60E transmissions.
I rebuilt mine and installed his whole shift package
It makes the trans work so much better.
Best of Luck.

Most shift-kits can be done in the garage with basic hand tools.

 

Agreed.

Rebuilding a trans to correct/strengthen it overall is the best route to go...

but boosting line pressure, in the mean time, on a stock tranny will help it last longer. Plus, it is quite a bit cheaper and easily done. I've got 197K on the stock tranny right now. Plan on a rebuild soon when funds allow and have been reading up on various parts/packages available.

The link Blazer Steve put up is a great one. Added to my favorites.

 

I think he's talking about the plug and play shift firmness increaser from B&M. Supposedly you plug it in (where, I dont know) and theres a selector lever that you use to get the desired shift firmness. 0 is stock, 1 is a moderate increase for street/strip, and 2 is very firm for towing and the like. I will eventually buy one, seeing as theyre only about 35 dollars from Summit. FYI I would drop the trans pan first and see how your rebuild is holding up before adding anything to the trans.

 

You tap into some wires form the ecm, and I have one in my truck and love it!!

 

just put in yesterday and works great! you just have to have the engine off to switch modes. took me about two hours, but im VERY peticular about neatness and not being able to see wires so it could be done faster. mode 1 is towing, mode 2 is street/strip anf off is factory, i will probly leave it in mode 1 from now on (til i get the pcm tune) just for the fact that it keeps the clutches from slipping like the 4l60e is designed to do for a smoother shift. little more stress on the drum but nothing that worries me and i just dropped the pan for a svc about 2 weeks ago and all seems fine.

this is a GREAT idea for a stock trans and gears!
