93 grand caravan le trans lacks high gear
when I get on the freeway the van rpm's go to 5000 at 60 mph. Fluid added it works. 2 days later check gauge light on and it won't dshift into high gear. Problem last year was relay that affected rear back up lights at firewall. How to service the trans? It's a 93 3.3 engine with 190000 miles and has been pampered.
You're getting into an area where you might start to see major things going wrong with your car. I would try and find out why the check engine light came on. Take the car to an Autozone and have them hook it up to the computer to see what the code says.
