Hi guys i am having an issue with my 2000 GMC Jimmy 4x4 i have recently replaced the radiator, alternator, thermostat, battery.
Before changing the radiator i had a very minor leak and would only leak when driving while pressure was built up but i would notice if i drove for an extended period of time like on the interstate and then got off at an exit and stopped then started going again my transmission would hesitate from 1st to 2nd and then be really hard into the next gear. It didnt happen all the time only 4 times in like a 2 month span. (and i drive interstate daily 50miles to work)
It completely stopped doing the hesitation but now when driving it on the interstate it really doesnt want to go over 60mph it shifts through all the first gears clean as a whistle but when i get up to speed on the highway or go up a hill it seems to lose all power will rev up to 3500rpm and not shift into the final gear. I can let my foot off the gas and it feels like it shifts but i think it is just locking in the last gear because i will get no speed gain from it if i hit the gas afterwards it just revs up again and holds.
Now i have been driving it like that for sometime (i know just been to broke to do anything about it). a couple days ago i was finally able to change out the radiator and it seemed to go fine except i couldnt get the bottom shroud back on with the new radiator seemed like the radiator was slightly smaller then the shroud could fit in so i just took it out.
Now i have a transmission fluid leak when i drive it and it sprays my whole passenger wheel well and then drips from right under where the radiator is on the passenger side.
I think i may have knocked something lose while changing the radiator.
Anyway sorry for the long post i figured background info was useful
My questions are : Any suggestions as to where the leak may be coming from? I checked all hoses i messed with while doing the radiator and they seem ok.
Also what is causing my truck to not shift at high speeds?
also forgot to mention when i crank it it has a loud noise coming from the bottom of the vehicle (i cant pinpoint where) that sounds like a can of shrapnel being shaken and its a sound that is always present when i first start the vehicle but then it dies out if i drive for a while.
Thanks!
