1 Answer

86 Grandprix it shifts gears to fast andI get no torque

Very shortly after take off it shifts to 2nd. Then before the rpms get up it shifts again. Drives great on the freeway, but city sucks . Car wont down shift properly sometimes it stalls during fast stops.... just like a stickshift when you stop in 2nd gear

    sluggish shifting into 2nd gear. sounds like going back down into gear.

  • Anonymous Apr 01, 2014

    I was driving and stopped and went to go again and there was nothing. I never had any tranny problems but it now will not go into any gear. Could the shift linkage come unhooked or some ideas what it could be????

Get it scanned for soft codes.... likely a VSS (vehicle speed sensor) out or shift solenoids for trans

Trouble shifting into 2nd gear and reverse but drives good once it shifts?


No not the whole transmission. Could be a band or servo. It still has to come out and be tore down to fix.

I recently performed a transmission fluid flush (pan and torque converter) and swapped out the filter due to some problems I was having shifting from 1st to 2nd. After changing the fluid, the problem was...


One thing that is rarely posted is any repairs and or instructions on doing so. For instance the Solenoid pack is often suggested as a replacement, and you can buy them on e-bay, but no instruction on how to replace one. Amazing. I can fix anything! Just take it to the Tranny Shop..... Makes me think that the only answers put on here are by Tranny Shops.

Will not shift into 2nd gear on a automatic trans


Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmision is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

What is "limp-home mode" ? This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

Thank you for using fixya and good luck

I just replaced all the belts on my 2000 Kia


The last shift is not a real gear shift, it is called "torque converter". The high rpms happens because the transm. goes to neutral. Get it to a transm. shop to be tested

Transmission will not shift out of 1st gear.


Check your transmission fluid level. If the filter has never been changed, now is a good time to replace the fluid and filter.

1998 Dodge RAM 1500 won't upshift, slips out of gear


have you dropped the pan to see whats the bands are set at, any debris in pan bottom, whats your governor pressure, if bands are ok, but gov pressures are not relative to speed 1 psi per mph up to 95-127psi, port is on pass side of case rear top right, scan tool would be very helpful, your must have mil light on for this problem, gov dtc's, replace gov transducer as gov solniod as a pair, no exceptions, also are there any 02 sensor dtc's, shorted to voltage, this wil make pcm do stupid things to trans shift, affecting gov signals. GOOD LUCK RDJRP

I have just bought a 51 plate a3 1.8. Sometimes it wont go into third and fifth gear as it should. When trying to change into these gears it doesn't crunch it just won't let you put it in gear. The best...


The possiblities that come to mind are
1 Bad synchro in transmission 2 bad bearing(s) in transmission input shaft.   3 Bent shift linkage or shift fork (I doubt this, but it's possible)
Only number 3 is relatively cheap.  I'd go back to where/who you bought the car from, if it was that way when you bought it, and ask them to help.  It can't hurt.

Using force is NOT the solution.  If the syncros are bad, until you get them replaced, you'll be better off to determine the RPM difference between 2&3 gears (maybe 800-1000?) and also 4&5 gears (maybe 500-800?) and learn to put a modest amount of effort at exactly the time the rpms fall into that diffference.  
Example Say the difference between 2nd gear at 3500 RPM and 3rd gear is 1000 RPM, then when you take it out of 2nd for an upshift to third,  delay until the RPMs are just getting to 2500. If you are on a budget and can't fix the transmission (it's going to be big bucks) you may find you can get pretty good at this.    It is possibly to shift a car this way without even using the clutch, although I don't recommend this and it takes a great deal of practice and luck.
While you have this problem, don't downshift into 3rd,  just run the RPMs down in 4th (say to 2000 or less) until you can shift into 2nd at an acceptable RPM. The least amount of shifting you can do until you resolve this the better.
Another choice until you can fix it, is to just run up the RPMs in 2nd and then shift to 4th, and then forget you have a fifth gear.  This is much better than forcing, it's possible to do more damage by forcing. 
Is it hard to get into 3rd from 4th AND 2nd?
