Won't drive or shift in 3rd gear but will reverse first and second gear

If it won't shift to 3rd and stays in second, bad shift solenoid/s. If it shifts and the transmission drops out(high RPM's), the bad clutches in the transmission. Rebuild. Solenoids around $600 to replace. Transmission rebuild around $2200.

My 2003 new 325 I auto won't drive when put in gear

Could be electrical or the transmission is dead. If it just quit on day, then electrical. If it has been giving problems for awhile, like slipping and hard or missed shifts. Then rebuild the transmission.

When i put truck in tow haul it wants to start down shifting and wont up shift

Your transmission computer is telling the transmission that the load for that gear is incorrect and will automatically put the transmission in the gear that will not overload your engine. Most of the time when you are going up hill the transmission will do the same. It is just trying to save you an engine rebuild.

2002 buick rendevous awd tranny wont shift out of first gear

let transmission shop do pressure test and diagnostic check.many things will cause transmission not to shift right.could have faulty over drive solenoid.faulty VSS sensor it controls shifts. could have faulty TPS sensor or TCM.the first and second shift valves or solenoids bad your transmission is electronically control many things will cause problems the transmission shop use scanner to check out all shift solenoids.the older transmissions use modulator valve and governor valve control transmission shifts but the newer transmissions shifts control by TCM and ECM.

I have a 97 chevy silverado c1500 ext cab 2wd automatic the truck stopped shifting. I had a tranny rebuild done and then park reverse and neutral worked but it wouldn't shift outta 1 st. Got new shift...

1st and 3rd gear only sounds like a broken sun shell he should feel bad... The only real issue on those 96 97 transmissions is the solenoid resistance values so swap ur solenoids with the one u want to put in and it will work fine if u do ur home work first.. U got to know why they wont work thats how u find cheats... But first and third sounds like a stripped or sheared shell...was reverse gone to

2000 Pontiac Montana . Goes into gear hard when it shifts. Has 140000 miles on it.

It sounds like the pressure control solenoid inside the transmission. With that many miles I would suggest going ahead and rebuilding it. You need to remove the transmission from the van anyway to replace the solenoid. I have rebuild several of these, be sure to put in a shift kit, it makes a big difference. I've rebuilt them before and wasn't happy with the way it shifted, so I pull it back out, put in the kit and that did the trick. So, needless to say, I always put the kit in the first time. Although, I do know a guy that changed his filter and added some Lucus oil treatment for the transmission to the new oil, and he says he hasn't had that problem sence........makes me wonder.

Transmission is not shifting into third gear. I

Generally, if a transmission shop has told you that you do not need a new transmission, you do not need a new transmission. Let them replace the shift solenoid (they won't have to remove the transmission to do this, just the pan, fluid and filter) and tell them to use the Sonnax Heavy Duty 2-3 Shift valve as well (this can be done without removing the transmission too).
Then if it doesn't shift, you will need a complete rebuilt. Tell them you want a new torque converter, a hardened input shaft, a 29-element Borg-Warner input sprag, The Beast sun shell, a new reverse drum, an extra wide Carbon Fiber power band, a Sonnax .490" Boost valve, a Sonnax cast-aluminum pinless forward accumulator, the Sonnax "Super Hold" 1-2 and 3-4 servos, all Alto Red Eagle frictions and full-thickness Kolene steels, as a minimum over a stock rebuild. 4L60E's are weak and die at about 100,000-150,000 miles, sooner if you tow regularly. This build will cost you about 500 bucks more than a stock rebuild, but you will then have a bullet-proof transmission.
