Engine/Transmission (1998.5 - 2002) auto/trans shift

[JRTucker]

1999 stock truck with auto trans and 4:11 rear. trans. works fine except for shift from 2nd to 3rd - often requires release of accelerator for it to shift. Notice it seldom does it when pulling a load and most often does it when proceeding straight from startup - turn right or left and start up and it rarely does it. ??? thanks for any suggestions

When i bought my truck it had a worn out transmission and my 4th gear shift was like that, i would have to back out of it to shift. I took the valve body out to do a shift kit and found the 4th gear accumulator spring broken and wedge in its bore. After the street/strip kit it shifter like a mo-fo!!

I think in the 47RE the 2-3 shift is control by some rod (can't remember the name of it) and a spring. You might of broken the spring or rod. I'm not an expert and haven't dove deep into the 47RE (very soon though).

When you mention it doesn't do it if you turn left or right it sounds like a loose electrical connection. I wouldn't know where to look for that though.

Good luck!

thanks - I'll keep looking and asking until I find something - trying to stay out of a transmission shop as they always seem to have to do a complete rebuild to fix anything.

I have been "playing" with the TV cable working toward the same end solution. I think my TV is too tight and have been loosening it in micro steps and seem to be going in the right direction.

have you tried this?

If you have the ability and the tools, change the fluid & filter. Wipe the pan out, use a clean rag, like an old but washed t-shirt, and some brake-kleen. Or use lacquer thinner. Rinse well with soapy water, then hot water, then blow it out with an air gun. And then, adjust the bands. If there isn't one there now, put a magnet in the bottom of the pan before you bolt it back up. Many autos have one from the factory. It will catch aluminum particles, regardless of what we learned in 7th grade about ferrous and non-ferrous metals. This is critical, because they do wear with regular use. And the procedure has to be done properly or more harm than good can result. Before you panic and start a paper route to pay for a new trans, if you haven't already done so, do some regular maintenance. If you don't have the ability or desire to do it yourself, try a reputable transmission shop. Food for thought.
