Ending rev’s up when foot is off the gas pedal!

[The Grey Beast]

So I posted before that I have a transmission that catches or jerks. So I’ve been noticing that when I rev the Engine and speed up then slow or stop as I’m breaking the engine will rev up to 1k 1.5k Rpm’s then stop all together and idel. With out my foot on the gas. It’s like a delayed response.

Hope I made sense.

First things that come to mind is, any CEL? Last time throttle bore and MAF were cleaned? Possible TPS problem?

By the way...year...engine...model?

Might want to edit the title of thread, unless you really wanted to say "ending" instead of "engine".

Please help. I have the same problem as of yesterday. 2011 suburban rwd. Transmission shift fine all the way throug the gears and runs perfect. It's when I come to slow down and stop and take off it acts like it's looking for first gear for a second then catch and CLUNK takes off. Fluid was dirty but changed it and filter. It's still doing the same thing. But if I come to slow down and completely stop for about 3 seconds it goes in first and takes off just fine.

It's like it's looking for first gear then finds it.

Maybe @NickTransmissions can help? Maybe @rockola1971 can help?

Please start a separate thread in the same sub-forum instead of hikacking @The Grey Beast 's. His thread concerns engine / engine mgmt issues whereas yours is specific to the transmission.

Tag me in the new thread and ill respond when I see it.

I responded in your thread - please respond to my ?s there...TIA
