I bought a 2001 GTS celica. It needed a transmisson. Its got 124k. New trans(used with only 50k) auto. just installed about 2 mths ago. I dont know if the car did this before the transmission. But when its cold (engine) the rpm's will not rive up. nor will it get up to speed. but after it shifts up to about 3rd it takes off. But even when its sitting still in neutral or park it still will not rive up. Once the car has been driveing a few mins. u can cut the car off. and wait a few mins get back in and its fine. But if the car sits a while and gets cold it wont rive up or get up to speed good. Any suggestions?

Re: slow to get up to speed, or rpm's up.
You probably have a broken retainer pin on the VVT (Variable Valve TIming) controller, which is located inside the cam area on the cylinder head. Not something that I would fool with if you have no experience removing the cams. Best left to a professional. Unfortunatly, quite a common problem, I have done 6 this year.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

or or cold engine? or both./
did you check the TCM brain for scan codes
this year, is either the jumper and bulb flash trick
or use any real OBD2 (USA?)_ scan tool to see all scan DTC codes
P07xx car trans.
alldata.com covers this, why not log in and look.
1: check all fuse
2: check trans levels using oper. guide method , hint dont guess.
3: run scanner, (or flash code checks on TCM)
4: do the 50k mile full fush and filter change now, if not too late.
lots more, tell more get more.
Not driving a corvette? Just kidding. More details are important. How slow is your acceleration? Is it 0-60 in 8 seconds, or 20 seconds? What is redline on your car? If redline is 5K then 4000 is a good responsible shift point. If redline is 8K then shifting at 4000 is probably robbing your engine of it's torque and horsepower band. I believe the GTS model has an 8K RPM redline, the GT may be lower, but in that case, shifting at 4K is too soon for strong acceleration. Your Tachometer should have redline clearly marked. For responsible use, stay below that, maybe 10-20%. For economy stay further still, but for power you need to let the engine use it's RPMS, especially smaller and fewer cylinder engines usually don't make their power until they are half way through the RPM range and above.
With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.
if its manual sounds like your clutch could be slipping does car smell of burt clutch?
check cluth adjustment
may need new clutch
do stall test with hand brake on, foot (heel-toe) on brake and accel pedal to about 2000rpm then let out clutch and car should stall if engine revs go down and engine still runs but you can rev causing slip and you will now smell what slipping burnt clutch is replace it.
if its auto check trans oil level and what does it look like red-good
darker red to black-bad often smells burnt also possibly new trans required.

strip out auto box and fit a manual gearbox ,this is an expensive repair by the sound of it,is it a manual pump in the box?? or has it had an electric one built in to keep the pressure up as i have seen this on *** cars ,good job not many autos in spain ,macho men here only old men from northern europe buy an auto and they are very expensive and difficult to get
i paid a friend to do it because it's a lot of work! if you haven't already treid to or got it done just know that when my friend did it; it took him like 8 hours (he'd never done one on a celica, but had done them on american cars) so if your not familiar with it... not a good idea to do alone. I watched him do most, but i'm not the best to talk to about it.(plus i have a 2000GT) Some of the parts that i can remember that he took out to get to the clutch were the front driver's side tire, the axel on the same side, ....some other parts in there....and ALSO parts on top...the intake also had to be taken out just to have enough room to do the job. parts are cheap...just ask for a clutch kit at auto zone or whatever. around $150. another random tid bit that might help is make sure to tighten the engine mounts really good afterwards or else it will jump around in there when you turn it on and cut it off. buy gear oil before you start as well because you will need to put some in after the new clutch is in. i will need to put the car on a real lift... you need a lot of space underneath and on top to work. and most likely two people. well hope some of this helped.
