Question about S10

90k is nothing for the 4.3 which will easily run to 200k; the 4L60e transmission is decent IF the prior owner changed the fluid at regular intervals and didn't haul anything too heavy with the truck. Can't answer the question if it's a bad investment as I haven't seen it and don't know what the sticker is.

My buddy just bought a 00' Blazer w/75k and he loves it. Great little SUV's.

Doc

don't forget about the 'TCC regulator valve time bomb' in the 60E's

at 90 k he's on borrowed time if it hasn't been fixed yet

Given fluid and filter changes every 15k (Mobil 1 ATF and OE filters) and ZERO hauling on a 98' Sonoma SLS (the wifey's truck), how long the TCC regulator valve hold out? What about the nefarious P1870. How long with perfect maintenance does one have?

Doc

the

I see them about 50-80 k, regardless of maintenance history

The P-1870 is a result of the TCC regulator valve wearing the VB bore

Gary, How bad is that valve to replace Before problems. Best solution you have found?

well, since the wear is in the valve body itself, it must be replaced with a valve-and-sleeve combo

I bought the reamer to do it, since I see anywhere from 3-8 a month

If you catch it right when it starts (first instance of code P1870 appearing), reaming and sleeving the valve body will fix it

If you keep driving it, it doesn't take long to fry the converter clutch lining

Best solution? Take it to an independent transmission shop that does a lot of trucks, ask them if they can do the 'Sonnax' repair to the torque converter regulator valve

Is this a problem also on the 1995 Blazer? (new body)

OK, OK, OK. I had a '98 that I got rid of because of the studdering and then the hard shift from first to second. It was that valve, I believe. I bought my 2002 with a stick just to make sure I didn't get that problem again. My question is: Why hasn't GM just done a total recall and then fixed the thing from the start. Maybe put a sleeve in from the factory, etc.?

Thanks!

Because most of them blow after the warranty is up so they don't care?

Does the tranny have to be pulled for this repair? Now I've got something else to worry about.

Mine blow last march with 20K on the clock! Luckily it was under warranty.
