My Explorer has 190,000 miles on it which are mostly freeway miles. I've been leaking transmission fluid for sometime now and one repair shop told me it would be around $750 to replace all seals and gaskets but with my high miles he thought that that would be a waste of money and that I should just replace the transmission for around $2,000. My only problem is the fluid leaking and what I believe is a factory defect with the transmission. (if going up hill with cruise on say at 65mph the transmisson will downshift with a strange noise coming from the transmission-kinda like the sound you hear going over rumble strips) Other than the transmission slipping when the fluid gets too low I don't have any problems. Is it a waste of money to put $750 into a transmission with 190,000 miles? Once again, mostly freeway miles. I'll probably keep the Explorer for a while and I average around 25-30,000 miles per year. (I use it for work but may be getting a company car soon-my 14 year old daughter has called dibs on it) Any input would be greatly appreciated. I don't know much about transmissions but if you have any questions about repairing medical x-ray equipment I'm you man.
I had a 89 Chevy Blazer that I put 310,000 on in around 10 years (and still sold it for $1,000) but it had a manual transmission so I'm an auto transmission noob.
