i blew my trans in my 2000 T/A, i hvae about 520rwhp i can get a 4l80 for cheap or a turbo 400 for a good price that is built up, whats should i do, im putting a 4200 stall in it,

4l80e is it strong enough stock or should i go with th400?

please i drag race the car an drive it, need assistance trans is out my car already need a direction as what i should do my car cannot be down for every!!!

 

FWIW a 4L80 is basically a TH400 with overdrive... They are quite a bit more expensive to build and I believe that you need some sort of electronics (BS3 or a standalone box) to control it... Either one with hold quite a bit of power...

 

You can control a 4L80E with a tune change, I did mine with HPT and control it with the stock PCM.

I highly recommend the swap - just be aware if you're swapping from a 4L60E you will lose a little power with the swap but gain a lot more durability.

well im putting a th400 in it i think i just need to find out how to make my shifter work with the rmvb

 

Get a ratchet shifter from B&M or Hurst or something. You'll need one for a RMVB

 

get the 4l80 and have it built with a manual valve body, it will be a TON of fun and ou'll have the overdrive for highway cruising.

 

You can use your stock shifter, the shifter dosent know what trans its on, its just a lever that pulls the cable. You can get a P-R-N-1-2-3 decal made for the console cover that would look factory. Thats what I was going to do when I had my th400... I just decided to go 4l80e instead (I wanted OD)
