Intermitente starting problems & transmission seemed to go out the other day while driving it

sounds more like an engine issue off the top of my head. The transmission runs off the vacuum from the engine. If the engine timing chain is stretched it will run then not run, have problems idling and shifting and won't charge the battery properly. anyone who has done one before could probably tell you just by the sound of the engine running.

700r4 transmission, my transmission is doing high rpm before shifting up from 1st gear, but with no slippage in any gear, rest of the upshifts are firm.BUT, on kickdown from 3 to 2.gear its going as i

I don't know if this will help,but i set my tranny up to shift hard like you are describing. Just by putting a clip on the kick down cable. The book talks about this, its cool if you like that sort of thing?

1997 Chev. Z-28 Camaro shifts from 2nd to neutral sometimes, other times it does it from 3rd to 4th. Also won't downshift from 4th to 2nd in drive. trouble code 1870 appears, transmission has been rebuilt...

code p 1870 refers to transmission component slipping
the transmission may need clutch and band adjustment or a pump pressure test check as it may not be producing enough pressure to keep components in place

U151e sienna transmission shuttle shifts 2-3 3-2 and 3-4 and 4-3 on an up shift. Happens quickly. Like its searching between shifts. Thank You

It could be the speed sensor in the transmission but sounds more like your transmission is slipping.Hopefully it is the sensor.If it ends up being the transmission is bad though,I have experienced problems with longevity/durability with rebuilt or used transmissions.Buying a new one could be between $300-$500 more,maybe more,but is well worth the money.It will probably only have a 1 year warranty,rarely a 2 year but it is there.I also know other people who have had them rebuilt and it was very disappointing considering the money involved.When I researched replacing a clutch versus a transmission,I switched to manual transmissions and have had them ever since.About 6 years ago,I got a new clutch for $500.Good luck,Greg

there are shift forks in the shift linkage inside the transmission that are worn because you rest your hand on the shifter between shifts and while waiting at a light this will require the transmission to be rebuilt to cure then take your hand completely off the shifter between shifts and at lights when you are waiting.
If this information is helpful please give me a fixya! rating and anyhing else I can do to help this problem contact me by fixya or

Thanks, Randy
