My auto 90 xcab has issues in the morning if i don't let it warm up for 5 or so minutes. They've been getting worse. The last couple days it's been reluctant to shift up, reving far too high and then actually slipping in and out of what feels like neutral, but slightly different. I bought the truck about 20,000 kms ago. At the time, the engine jumped significantly when shifting until it wad warmed up. I replaced the engine mount on the side that jumps and its still happening. It used to just be sluggish when it was driven without idling a little first, but now it seems to have progressed into slipping out of gear intermitently. Once its warmed up it'll drive all day with no slipping or even jumping, but for the first 5 or so minutes it slips in and out of gear and jumps a lot. Has anyone experienced this sort of thing or have any advice? Any help is much appreciated!
if u haven't check fluid when hot and idling level ground . Should be pinkish not smell burnt make sure it's topped off Filter condition a clogged dirty filter can lower pressure causing shift solenoids to act funny What's the mileage on the trans
The early autos sucked balls. Nowadays it's flip flopped. The autos are great and the 6 speeds stink. If you think about it, you said once its warm it shifts fine. But cold it acts crazy. The trans uses fluid which is similar to oil. So it's thicker when cold and thinner when hot. The auto has a pump and a filter and a torque converter. If the fluid is old, the filter clogged from not being changed in a while, it's hard for the trans to pump it through all the ports and passages it needs to. But once it's "warmed up" the fluid becomes thinner and easier to be pumped and moved around in there. I'd do a fluid flush and a new filter. I think, as I have always had a manual, that you have a A340E trans which is the code for the auto, if they ask anywhere.
Yea also the a340 is plagued buy bad shift solenoids . This trans is used in several other domestic and foreign cars trucks http://www.toyotaholics.com/support/topic.asp?TOPIC_ID=19
Thanks a lot guys! I went for a tranny flush and filter change but the fluid was fairly dark and burnt smelling so the guy didn't want to do it, for fear that the thinner new fluid would create more gear slipping. He suggested going to a tranny shop and having them look it. Apparently though, I could change the truck to a standard?! That sounds like making gold out of dog **** to me! Any body gone through that before?
Ive done a couple auto to manual swaps on 4x4 yotas and its simple. You'll need the pedal and all the hydraulics along with the clutch etc.
yea there's guys that have done it find you a junkyard truck manual and remove all the manual pedals and do a swap trucks a lot funner that way . And isn't a really a hard thing to swap either
Thinner new fluid would cause more slipping? -_- You're putting in fresh fluid that would have fresh friction modifiers and heat protection. include lubrication, also. I destroyed my auto. W58 5speed swap. Transmission from a car. everything else from a matching 5spd truck. If you have a single cab, ****'s easy for you. get pedals, lines, everything. transmission mount, driveshaft. get a new clutch. I got a new master and slave cylinder for like $20-30 each, Exedy.
Yea new tranny fluid will kill an unserviced automatic . Trans fluid has detergent and friction modifiers the detergent cleans away the friction material on already slipping clutches .. The old fluid contaminated with clutch material aka (blackish fluid ) is what is helping the worn clutches get traction .. . If its flushed . It pretty much looses what was keeping it alive .. This happens in the industry daily and shops foot the bill .. Untrained or inexperienced techs are notorious for this The best way to treat auto trans is to blow them up set them on fire . Unless your drag racing with it
