Oh no...tranny woes

[Chopper]

Guess it's my day in the barrel. I changed the giant stock muffler out for a Magnaflow. The increased sound allowed me to notice a weird shift in the tranny It's nothing that can be felt...no slam, no slip. When the 3-4 shift happens, it drops into fourth smoothly enough, then a few beats later it drops another 300rpm or so...essentially feels (or acts) like a 4speed OD transmission. I've gained an extra half gear! The good news is, I am an O.O.,so Isuzu is married to me for the entire ten years(HA) and all maintainence has been overdone. Plus my Isuzu dealer is only 27 miles away. I just turned 30,000 so service is due anyway. I run Mobil1 everywhere, so that's not the problem(yes it's full) We'll see. (encourage me to do the Tropper stick transplant...keep everything, but gain a third pedal) I just HATE anyone else touching my car...ever...a real problem for me, but a warranty is a warranty. Won't kill me to play by someone else's rules...I guess. Love, Wayne

"Sounds" normal to me and mine has 106k miles.

Yup, I agree that's normal behavior. Feels like those two-step modulated OD shifts. My late-model Troopers did the same thing, although the '04 Axiom and its Aisin didn't.

You mean a tranny swap isn't called for??? Doggonit, I need another one, just so I have one to work on

I've got a couple of Fiat 5-speeds with bad synchros you can tinker with.

Leave your tranny alone, Chopper... I'm pretty sure that's just the lock-up torque converter locking up after shifts. It will actually do that when shifting into 2, 3, and 4, although you have to be fairly light on the gas to notice it in the lower gears. Mine varies in its behavior depending on load and outside temps, but it's normal operation. Someone last year posted a tongue-in-cheek thread claiming to really have 7 gears.

If you want to tinker with something, come on up to CT for a few days and we can rebuild the engine on the GT. :-)
