Poll for my transmission

[chrisok5]

my stall converter needs to be replaced because the current set up is using washers to make it fit and the converter seems too big as it feels like a drag set up.

If I'm going to have to pull the transmission to fix this, I figure I should think about just getting the transmission too.

Current set up:
5.3
TH350
NP205
14bolt 4:11
10 bolt 4:11
305/75R16

I vote for overdrive, might as well use the gen3 technology and do the 4l60e or even better a 80e.

You've already got a pcm, let it control the tranny too.

It's a blazer, too short for an 80 imo. 4l60e ftw

what no correct spacer for flex plate on crank shaft ?

and overdrive is the ticket anymore .

if you have a ls computer this would be the thing . 4l60-e . . . just make sure you can bolt your t-case up and also rear electric speedo option .

offroad design now offers electric speedo option for 205 t-case .

newer 4l60/4l65 use a 6 bolt tail housing so watch what 4l60 combo you get to bolt the 205 up .

or swap in a 241 from a 90-91 square body blazer/burban for good low range and electric speedo .

4.11 gear and 33" tires not a bad combo with non overdrive tho . so if your happy keep it then .

I had to go with the 4L60E, based on your K5's setup with the computer.

Will the 80 bolt up to the 205? Also, why is the blazer too short? In a sense that the heavy duty tranny isn't a good match for the geometry (or both).

Are you running a 205?

I'm sure it'll bolt up, but the 80 is a really long transmission. It'll make your rear driveshaft angle really steep.

Not currently, I've been on the hunt for a transplant vehicle with 5.3. I will be in your situation at some point but I'm pretty sure there is an adapter.
