Transmission Fluid advice
I know this question that im about to ask is a really noob question, and i should ask around (as i will tomorrow at a decent time when i get a break at work) but how much would it cost to get the transmission fluid drained from my T5 and replaced. The reason i need this done is because It has a very slow leak around the rear seal and ive yet to add Tranny Fluid. The car's shifting has gotten "Grabby" where it doesnt want to go into gear as easily as it should. I have replaced the rear seal twice, and the only thing i can think of is that either the driveshaft is out of balance, or the yoke is slightly bent, opening up the seal just enough for a very small leak. Based on my philosophy that If it is cheaper in the long run to keep adding fluid than it is to fix the leak (copyright lol) i think i will just leave the seal alone. Also i would check the amount of fluid myself, but the mechanic who replaced the rear seal last time impacted the fill plug on the tranny (I think) because I tried to climb under the car last night and loosen it and it wouldnt even budge, even after i hit the ratchet with a ball peen hammer.
On a side note, I read that the manual calls for Mercon 5 ATF. would it hurt my tranny if i used gas station special ATF?
