CAR PULLS SLOW IN DRIVE 1ST GEAR WITH ACCELERTOR DOWN

don't shift into 1st until stopped and 10mph or less is your down shift range to 2nd gear from 3rd

you might have a bad sinconizer in the trans

Check the fluid level and if it low top it up. However I doubt this will fix it. The bad news is that it sounds like your transmission has had it and the only solution is to get it repaired. Take it to a specialist transmission repairer for them to do a diagnosis, but expect bad news.

It has a siolinoid in the transmission that is suppose to gear it back down to 1st gear when slowing down or just pulling it in gear.

Try putting the transmission in low or 1st gear manually shift it down and try taking off as you accelerate shift it manually to 2 then drive. Did it take off like it should when you put it into low and then shift up or did you feel more power when it was in low if so it sounds like the transmission is not going into low gear but taking off in maybe second gear or even drive. When it takes off in any other gear but low it will start slow and sluggish and as you begain to gain speed it will start feel normal but thats because the speed matches the gear you in at that point.If my assistance was helpful please take the time to rate my assistance thank you.

Your transmission apparently is not downshifting properly. From your description, it sounds as though it is in 2nd or 3rd gear, which is why it is slow to accelerate. When you shift into 1st, it is starting off in 1st gear as it should. You probably should have a transmission shop check it out. Check engine light on?

worn shift fork. shifts linkage could be binding.

you should first check gear box oil ,level and clean filter.lee

Unless you have run over something or something has hit the linkage that you may possibly repair to adjust the gear locations to their proper place on the trans, you must get trans checked out.

the clutch is sticking could be worn out or needs adjusting
