99 32RH automatic transmission shift points?

[hear]

I also agree that automatic transmission maintenance is a task that has been neglected by many people on a lot of vehicles. It's a lot more involved than changing engine oil and filter on most autos. I remember when I was a kid a million years ago and people would tell you not to service the transmission if it was high mileage and hadn't been serviced as it would lead to transmssion failure. Man that was dumb. It probaby happened that way because the transmission was failing anyway and they decided to try to save it with a fluid and filter change and it ultimately failed anyway.

100%

I think a lot of that comes from the fact that unless you actually work on transmissions, you can be told literally anything and believe it hook line and sinker. And I bet even some trans techs believe that still. Not everyone in this world can critically think, even in the face of evidence.

Hi Folks, wanted to follow up here on the question originally asked. I'm also having trouble getting shift points right, I have shifts at low throttle happening around 1,500, and around 2,300 if I give it some gas. Feel a bit low and a little gutless. What do you all shift at?

What gears and tires? That also affects how it feels.

3.07 and 30's. All pretty close to stock

Ha, no worries, I've got a very thick skin!

Anyway, yes, that is exactly what I'm saying, set everything back to where God intended per the FSM. When I get a new to me vehicle, one of the first things I try to do is change all of the fluids. Anytime I change fluid in an automatic that has adjustable bands, I adjust them. It doesnt' get done very often, as the change interval for the fluid is pretty high, I think around 30-60k miles for the 32rh depending on use.....and yes, I have always just re-set them to factory specs.

That said, I do agree that it is something that has to be done carefully and properly and with the right tools. I have a relatively new, very fine 1/4" inch pound torque wrench that only comes out for sensitive adjustments such as this one. I agree that while the transmission is in the vehicle the outside band adjustment is difficult and deserves special attention.

It t is good right up until you put on redline clutches, kolene steels, and get rid of the plastic accumulator piston, add a mix of transgo and other parts, it can change how things work.

I pulled the valve body off the trans i pulled out of my jeep. Plastic accumulator piston is in 2 pieces, so i see why people replace this. I can possibly see how transgo parts might affect band adjustment depending on what is being modified, but changing the accumulator piston, and clutches and steels, assuming they are set at factory specs, it would surprise me that this would make any difference in how the bands are adjusted.

That said, I'm not an expert at all, and am more familiar with GM transmissons (350/400) which have no band adjustments, tho i have played with a mopar 727.

Ditch the pocket flares and heavy Chinese bumper next. Neither of those is better.

Exactly

99% it’s the TV cable adjustment. The remaining 1% is either the throttle valve installed backwards if you had a recent rebuild or a stuck governor.

@hear I’ve messed with the throttle cable a bunch and am confident it’s set to the procedure in the service manual. Can you clarify how to check for a backwards throttle valve or stuck governor?

The best way is probably by doing a pressure test as described in the FSM. When I had my valve in backwards, I could see it with the pan off; the tang on the swivel that actually pushes in on the throttle valve wouldn't even really make contact with the valve. It pretty much operated as if the TV cable wasn't even attached. That tang should start applying the valve the moment it even starts to rotate.

A sticky governor will show up as a problem in the pressure test. The governor is rebuildable without removing the entire transmission. You have to remove the t-case and then the extension housing. From there it's just a c-clip holding it on. I've never run into a sticky one, so I don't know what real life causes/fixes might be. Best guess would be insufficient lube, corrosion, debris, or maybe even the bore not being smooth enough to allow the counterweight travel. All things you'll be able to tell once you have it in your hand.
