I have a ’98 sport, with the 318. I bought it about 6 months ago, and it ran fine when I bought it. About 3 months ago, I noticed a leak from my tranny pan and changed the filter, fluid and gasket. But recently I’ve noticed something’s been causing my truck not to run right and it’s been getting worse and worse. When I accelerate its doest quite have the pick up it used to, and sometimes actullylaggs around before taking off,and it doesn’t always want to shift right. Within the last 2 weeks, I’ve noticed that I used to be able to run approximately 70-75MPH at about 2100RPM or so, and now am running about 2200RPM at about 60-65. Is my tranny going out or could there be other problems? And if it is in fact my tranny, what are your recommendations for repair/replacement on a semi tight budget. Thanks

 

I would check out the cat.....then go from there.

 

would my cat being blocked cause my truck to do that? and to check my cat all i have to do it check input and output temp's right? output should be hotter?

 

Sorry for asking but did you used the right tramission fluid when you did the change ? Mine was doing some shifting problem and I found some quarts of dexron III in the toolbox....

 

ya.... i'm pretty sure i used the right stuff, i knwo i replaced it with the right stuff, but i had a slow leak from one of my cooler lines till i recently replaced it... i did have to add more and im pretty sure i used the right stuff... maybe i'll flush it out anyways and start with new again... thanks.
