I have erratic shifting problems when i hit the gas the transmission misses at 20mph to 30mph! and the engine just reves when im on the gas. to get it to go i have to let off the gas and press back on the gas. only happens at 20mph to 30mph.
Van will get up 20-30 not then drag to shift into next gear slips in second. Changed filter and transmission fluid. Everyone says to get a new trans. But I'm gonna try some things out before spending that the solenoid maybe.... Any suggestions
Van Shifts hard at times. If I pull over and take key out wait 5 min. put key back in start up and drive away no issues
I have a 1998 chevy venture,when you driving it it changes gear great and after about 20 min it start jumping out of gear..the motor just free spend...when you stop and cut the switch off about 5 min. when you start it back it work great again and you be going down the highway it jumps out of gear again...can some tell me what the problem is..
Whining going up hills, hard shifts, was told need a new transmission from 3 different qualified mechanics!!! I did get the tranny flushed, which stopped the whining, but the transmission would shift up to 20 times, maybe even more anytime I went up hills. FINALLY ... I found this product on the internet that comes highly recommended. Seafoam Transtune. (This is the Transtune Product - not the engine treatment. I reads: Seafoam Trans Tune). So I go to the store and the guy talks me into Lucas. Sigh. So I put in Lucas and nada! Same problems. I wait a few weeks and this time I had to go to 4 different stores before I found this bottle of Seafoam Transtune. I have the best running van now. No hard shifts, no multiple shifts, no big dollar repair bill. Do yourself a favor, go get some, and put it in your tranny. You could save yourself a few thousand in repairs. Good Luck All.
Drive and third gear not engaging but when vehicle takes off on one and two can be shifted to third and drive
Hard shifting started at random only on occasion and not every gear. Did and fluid filter change and added a qt. of Lucas transmission stabilizer. Shifted perfect for almost a week then hard shifts came back only this time in every gear starting after about 10-12 miles of driving. The simplest way to check if the PCS is to blame is after the hard shifts start turn the van off remove the key wait 1-2 minutes turn on start driving, if the hard shifts are gone more than likely the PCS is the problem and it will need to be replaced. I have ordered the part waiting for it to get here so I can replace it. If you are not able to DIY take it to a transmissions only shop not a big chain that works on transmissions too. Cost will be between $600-$800 if done by a shop. DIY cost $150-$250.
changed the fluid because the van was not wanting to back up or go forward,but after awhile it goes but slips
Will not go into 1st gear....Hard shifts from 2nd to 3rd gear....Added Lucas but no result....Code says shift solenoid....the part is cheap ($20) but a real bi#@h to install. Looking at about $600 labor.
starts to pulsate as if it can't make up its mind whether to shift into fourth gear or not. From a stop, it rolls out gently to 3 miles an hour then seems to grab suddenly as if it had never shifted down to low gear when the car stopped.
New transmission at 145,000 miles...still not sure it has fixed the problem. Main computer was thought to be causing the transmission to fail. Also installed a transmission cooler.
While I have had issues with it on and off when I first step on the gas, recently, it has been shifting harder into each gear.
Shift in drive won't change out after that grinds trying to go will go but after about 25/30 won't change only sometimes
