Questions & Answers

Is this kit compatible with my 4x4 GMC Jimmy, or is it only compatible with the 2WD version?

It is compatible with both 4x4 and 2 wheel drive systems as long as the transmission is a 4l60E. The 4l60 transmission's interior is identical.

I was just curious if the 1870 code on my envoy was still valid. ?

Yes, it continues to function flawlessly. The customer for whom I built the transmission was extremely happy with it. It's a simple kit to put together, and it comes with clear instructions.

Will my 96 Impala SS have firmer shifts as a result of this?

It is conceivable. We installed the kit to fix a problem with a missed shift. Also, make sure the separator plate is in good working order. Ours had a ball check jammed in the plate, necessitating the purchase of a new plate.

Is this from the year 4l60e?

Any 4l60e should be able to accommodate it. This is an excellent set.

WORTH IT
5/5

The instructions are not very clear, but if you pay attention you can finish it. It also recommends that you upgrade your servos to metal ones if you have plastic ones, so you might as well do that at the same time. I didn't because it said so in the instructions, and we already had it apart, but it shifts very hard into second with the Corvette servo, and this kit barks the tires on my 5500 tahoe.

Not for the faint of heart; read the instructions before proceeding; shifts are fantastic.

Five out of five stars
5/5

All of my 4l60e rebuilds start with this kit. The transmission shifts are very confident and solid as a result of this.

Repairing the P1870 error code
4/5

The P1870 error code was fixed with this kit. I removed the valve body from my 1999 Chevy Tahoe LT while it was still running. I followed the directions and consulted my GM service manuals as needed. The changes are noticeable, but they aren't abrupt. This is a kit that I would recommend.

It worked well and was simple to set up
4/5

It worked well and was simple to set up. Unfortunately, it slapped a scap on another issue that the previous rebuilder failed to address. It's time to have open heart surgery.
