Last week out of the blue the reverse is acting up. Upon initial start I put in reverse and nothing, rev engine and nothing. When it comes to idle it acts like it wants to grab but as soon as I give it throttle, nothing. At first I thought it may have something to do with cold weather (but the 30*F we call cold here in La is nothing for most of you guys). Drove truck to work.
I managed to push it backwards in driveway to get enough room to go forwards and took it for a drive and the forward works fine, no issues. But no reverse. The more I played with it I discovered that when putting into reverse it takes about 1.5 secs to 2 secs to engage in reverse. If left idling it will go backwards. As soon as any throttle is given it releases and nothing, but when the rpms get back down to idle it re-engages into reverse. I did this about 20 times to confirm.
Car currently has 243k. I purchased at 227k. I have records from previous owner and the transmission was rebuilt/replaced at around 150k miles. I know that I haven't serviced the trans since I bought it and I think it would be a fair guess that it wasn't serviced since the rebuild. So it currently has approx. 93k on the rebuilt trans/fluids. I was thinking given the slow engagement and the release with throttle that it could be low line pressure, which could mean either low fluid or plugged filter. I don't see fluid in driveway at home nor in parking spot at work so I don't think its losing fluid, must be a filter. Planning to drop the pan, change filter, and refill with new fluid. Have to wait til the weekend so that the lift is available at a buddies house.
Given the symptoms presented, does it sound like im going down the right path? Is there something else I should be concerned with or look at? Again, any insight and information is greatly appreciated. Thanks in advance.
