Can i put a 5 speed automatic transmission ina 1990 Suburban V1500 4x4 in place of a 700r4?

it was a joke in reply to Bob... powerglides make a nice strip transmission for a car... other than that, they suck....


anything can be done man.. I'm sure there's modern 5 spd's behind sb/bb chevys.. keep in mind modern 5 spds are computer controlled.. it would need a stand alone comp for it....
 
The only 5 speed auto gm has is the Allison that came behind duramaxes and 8.1l from 01 to 05. Would be very expensive to install and need modifications to trans tunnel, driveshafts, cross members, and possibly other stuff.

Your next best option is a 6 speed from a newer truck. Such as a 6l90. Still going to be very expensive and like ryoken said is electronically controlled so will need a stand alone controller.

Honestly more money than it's worth. 700r4 is a decent trans in these old trucks.
 
Silverado has an optional 8 speed auto for 2016...

Personally I'm not a more is better kinda guy with Auto's. I felt the 700R-4 was 'busy', but the 6L90 in my '15 GMC is busier. I can't imagine an 8 speed.

I am not a big fan of the 6spd in my wife's Cadillac Escalade. It tries everything to keep the RPM's of that sweet 6.2 down super low and out of it's power band. I can be doing 35mph and it wants to upshift all the way to 6th gear and 1100rpm. It has to down shift 3 times just to get into a gear where it has some power to go from 35-40mph. I also don't like the way they act coming out of the hole. 1st gear, then a quick up shift into 2nd. I prefer a 4L60E that lets it rev pretty hard even with jjust moderate throttle position, going into 2nd.

That's how my 90 suburban v1500 shifts like your wife's Escalade. That's the best description of how it shifts . it shifts quick out of 1st, to 2nd with little to medium ease on the throttle.

The other suburban I had didn't do that. It was the same year with rear wheel drive and if steep on the gas LIGHT or moderate it will stay in 1st unless you step on it a little hard .

Lets say you're in the neighborhood and your going slow , and when you step on the gas light, or medium a bit it will stay in first . with the suburban I have now, you step light it will want to shoot up at the end of 1st gear quick before shifting into 2nd
 
Your TV cable isn't set correctly then. Soft stacked shifts is a huge red flag for incorrect TV cable set...

The 6 speed in my Sierra is the same. Love the truck, hate the tranny programming. That and the traction control...why have a switch to turn it off if it never actually turns off?
 
what Rene said...... every minute you drive that thing with an out of whack TV, you're hurtin it... if the line pressures are really off, you'll nuke it in short order..... super simple.. depress the "D" button, push the sheath all the way to the firewall, release button, mash gas pedal to floor...

nothing wrong with a properly built/upgraded 700.. properly built being the key term...

unless your committing to an ENTIRE modern drivetrain and all the custom work involved in getting stuff like that to work, fix and upgrade the systems you have... that's what I did the first 10, 15 yr's of building vehicles...

I'm might just stick with My rebuilt (back in Nov 2013) 700r4
 
Good plan, but if you don't want to have to rebuild it again soon you should get the TV cable set correctly.
