I would just find a different shop to rebuild yours. 2 in three months is horrible.

That sounds like whoever built it messed up pretty bad (unless you're making some obscene amount of power). But, to answer what would swap without breaking the bank other than a 700r4/4l60, a TH350.

You'd need a crossmember that has the torque arm relocation mount, you'd need either the adapter to run your speedometer with the TH350 speed sensor, or run your speedo off one of the front wheel hubs. Also it needs to be a long tailshaft trans.

I have been running a Level 2 in my car for over 2 years now and it's taking the beating just fine. It's ALL in the builder.

Keep in mind that a TH350 doesn't have an overdrive gear, so if this is your daily driver you may want to reconsider swapping in a 3-speed auto.

I have had a ProBuilt Automatics 4L60E in my car for over 7 years, car was already cammed when the tranny went in, then I think it was 5 years ago I stepped up to heads and cam making over 100hp more than I had told him I ever planned on making. He had me redrill one hole in the separator plate to improve the 1-2 shift for the added power.

Mine even still has stock servos, stock sunshell, stock planataries, not really any special parts, just a good assembler.

Those of us who are successful with things work THROUGH problems when we have them rather than turning away and not learning anything.

I used Probuild Automatic's 675 hp pro street kit for mine. After we built it, the car drove extremely docile until you hammered it, then it really woke up.

The only reason I dropped the 700r4 for the TH350 is because now it's a weekend warrior car.

First thing is to decide what you are going to do with the car. For the street, rebuild the 4l60E, except do it right. If you're near Tucson PM me.

If I drove mine on a day-to-day basis, I'd stick with the 4L60. Just do yourself a favor and ask around for a reputable shop in your area to do the build. If you want a little extra on the performance side, have them install a shift kit.
