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.
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.
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

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.

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.
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.
No shifting from high to low it stay high

While driving i could feel the gears slipping at random times and some times when i step on the accelerator it feels and sound weird
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
tranmission expert advised it is not worth fixing as it requires alot of disassembly and replacement of fluids which can cause further complications when the trans has this high mileage. The sticking of the solenoid and resultant hard shifting and pump whining can be temporarily remedied by shutting off the van for several seconds which usually resets the solenoid and then the car will continue to run smoothly again for sometime. I just wait till I get to a stop and then shut off the car and restart and keep going. Been driving it like this now for about 10K miles. Trans expert said it's possible I could get 50K more miles on the transmission even with this problem, but no guarantees of course.
When accelerating the van makes a whining sound and bucks when shifting.
when it's up shifting or down shifting its hesitating to go into gear and jerks and then goes into gear.
The car will shift into all gears but park
Tranz or engine whins between 10 n 25 mph. Slowly builds speed yhe just roars up to the 50 it shohld be goin nk jerks just a slow creep to a bkg roarin chevy v8 i did notice it was eztremely bad thks morning and it was extra foggy out as well to nuch air moisture to motor ? Or tranny sensor plz help
changed the fluid because the van was not wanting to back up or go forward,but after awhile it goes but slips
Suddenly idles very fast, or when you are driving, van accelerates very fast. I have to immediately pull off the road and shut van down, wait and restart it. This has also happened when I was in reverse, parallel parking. Very scary, and dangerous.
It's not fixed yet I'm trying to find the problem. Its not letting it shift into high gear
when driving it starts slipping just like you put it in natural . you half to stop shute it off and restart it and it will take right off. it mite go20 feet or 10 miles you never no
